Unfortunately, FreeBSD NFS is unusable for us without oneopenown due to the issues with CPU load once enough Opens pile up. (I think our issues may be at least part of the reason you added the line about shared libraries to the man page.) > If you cannot get rid of the "oneopenown" or apply the kernel source patc= h, > getting rid of the nullfs mount or enabling delegations might also work a= round > this. We're not using delegations because of, "This can only be enabled when the file systems being exported to NFSv4 clients are not being accessed locally on the server." The filesystem is exported read only; updates are infrequent but must be atomic, so they are performed via ZFS snapshot receive on the server. There are two reasons we have been using nullfs. Both are related to our use case: large number of jobs (jails) where this filesystem must appear. The first and simpler issue is reserved port exhaustion. However, the filesystem is read-only and we've made a change on our end to make it the only filesystem exported from that server. So it should be perfectly safe to mount noresvport; that is a very solvable problem with a few changes to our code. The second issue is filesystem caching. With one NFS mount the client machine can (theoretically) keep one copy of the most frequently hit content from this in cache for everybody. If that's the behavior with nullfs but not with separate mounts, switching could lead to an increase in RAM usage or network traffic enough to adversely affect performance. What do you think? If an NFS filesystem needs to be mounted in 300-500 different places, is it better to NFS mount it once and nullfs it 500 times or better to NFS mount it 500 times? You certainly know vastly more about the likely implications than I do. I will find a way to try the patch. Thanks!

It seems that only on FreeBSD ERESTART == TRAVERSE_VISIT_NO_CHILDREN == -1. From a quick search, Linux and illumos use positive numbers for ERESTART. The potential problem is that dsl_process_async_destroys uses bptree_iterate to traverse blocks of a destroyed dataset. bptree_iterate internally uses traverse_dataset_destroyed and all the common traversal machinery. If dsl_scan_free_block_cb decides that the async destroy activity should stop (pause) in the current sync pass, then it would return ERESTART. traverse_dnode can misinterpret that return value as TRAVERSE_VISIT_NO_CHILDREN and stop visiting data blocks while continuing the traversal. As a result: 1. bptree_iterate may continue traversing despite dsl_scan_async_block_should_pause; 2. bptree_iterate may believe that it visited data blocks when, in fact, they were skipped. A test would require destroying a large enough dataset (on a throwaway pool), waiting for feature@async_destroy to switch from active to enabled and then checking that the pool's freeing property is not zero.

At the > very least, the call stack is the same up to nfsrpc_lookup+0x87f. It is probably caused by the same underlying bug. If you can easily get the source line# for nfsrpc_lookup+0x87f, that could be helpful. The only way I know of to do it is with a kernel.debug. What I do is: nm kernel.debug | fgrep nfsrpc_lookup --> Then I add 0x87f to the above hex value. addr2line -e kernel.debug - enter the hex value for nfsrpc_lookup+0x87f If you do not have a kernel.debug, maybe someone else knows a way to do this? But, if you cannot do it, I suspect the patch will deal with these as well. (The patch disables doing Open in the same RPC as Lookup. It is just an optimization and is only done for "oneopenown".) rick > > Fatal trap 12: page fault while in kernel mode > cpuid =3D 0; apic id =3D 00 > fault virtual address =3D 0x28 > fault code =3D supervisor read data, page not present > instruction pointer =3D 0x20:0xffffffff809da260 > stack pointer =3D 0x28:0xfffffe0111f18438 > frame pointer =3D 0x28:0xfffffe0111f18470 > code segment =3D base 0x0, limit 0xfffff, type 0x1b > =3D DPL 0, pres 1, long 1, def32 0, gran 1 > processor eflags =3D interrupt enabled, resume, IOPL =3D 0 > current process =3D 14676 (sh) > rdi: 0000000000000028 rsi: fffff80071cee200 rdx: 0000000000000000 > rcx: 0000000000000000 r8: 0000000000000032 r9: fffffe0111f19000 > rax: 0000000000000000 rbx: fffff80161e4b000 rbp: fffffe0111f18470 > r10: 00000000000001f4 r11: fffff8024e1e5760 r12: 0000000000000000 > r13: 0000000000000000 r14: fffff80071cee200 r15: 0000000000000000 > trap number =3D 12 > panic: page fault > cpuid =3D 0 > time =3D 1727064012 > KDB: stack backtrace: > #0 0xffffffff80b7fefd at kdb_backtrace+0x5d > #1 0xffffffff80b32bd1 at vpanic+0x131 > #2 0xffffffff80b32a93 at panic+0x43 > #3 0xffffffff8100091b at trap_fatal+0x40b > #4 0xffffffff81000966 at trap_pfault+0x46 > #5 0xffffffff80fd6d48 at calltrap+0x8 > #6 0xffffffff809f9eef at nfsrpc_lookup+0x87f > #7 0xffffffff80a0e2fd at nfs_lookup+0x43d > #8 0xffffffff80c0341a at vop_sigdefer+0x2a > #9 0xffffffff8302c3a7 at null_lookup+0xc7 > #10 0xffffffff80c08745 at vfs_lookup+0x425 > #11 0xffffffff80c079b8 at namei+0x238 > #12 0xffffffff80c2d2da at vn_open_cred+0x53a > #13 0xffffffff80c239a8 at openatfp+0x268 > #14 0xffffffff80c236b8 at sys_open+0x28 > #15 0xffffffff810011c0 at amd64_syscall+0x100 > #16 0xffffffff80fd765b at fast_syscall_common+0xf8 > > I don't know if this gives any more insight or confirmation to your > theory about the problem, but it seems worth sharing. > > We got three of these panics (and two of the first kind) on different > machines in the past 24 hours, so I'll definitely at least be > experimenting with bulk NFS mounts instead of one NFS + nullfs bulk > mounts in addition to trying the patch. > > Thanks!

Sure. I did it via lldb and got nfs_clrpcops.c 1697. Your method gives the same result. According to the github version of 14.1-RELEASE, that's the "if (ndp !=3D NULL) {" after the call to nfscl_openrelease(). Per lldb, the actual instruction at that address is: testq %r13, %r13 My knowledge of amd64 assembler is nearly nil, but I *think* this corresponds to checking if ndp is null. And I think that %r13 is a register, so I'm not sure that could cause a page fault. Maybe the trace indicates that that's the line it would have come back to if something in nfscl_openrelease() hadn't gone wrong? Thanks!

It is quite possible that this problem caused the other (hang I think?) that you reported before. A few years ago, I tried to avoid the extra RPC of doing an Open after a Lookup, by combining them in the same compound RPC. It turned out this did not work for multiple open owners, so it was only enabled for "oneopenown". (Since few use this mount option, I have not seen issues with it reported by others and it worked ok for my testing.) However, I now realize that Open works because a vnode lock on the vnode being opened guarantees that the Open does not go away during the VOP_OPEN(). Unfortunately, for VOP_LOOKUP(), it is the directory that is vnode locked and a vnode lock on the file being looked up is not acquired until the Lookup reply is processed. --> To fix this, I think I need to delay the open processing until after the vnode lock on the file has been acquired or --> Just back this Open in Lookup patch out, since it can only be made to work for "oneopenown" and it only reduces each Open by one RPC. The trivial patch I posted just disables the Open in Lookup RPC optimization, so it should have the same effect as backing the patch (it is actually several git commits) out. The good news is that it looks like I finally know why you were having problems others were not reporting. (I have no idea why 14.1 is crashing when previous versions would hang, etc, but crashes are much easier to diagnose.) rick > > > John Carr > From nobody Wed Sep 25 10:10:43 2024 X-Original-To: fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4XDCD4041Cz5XG50 for ;

We set up a version of our code that mounts the requisite NFS filesystem directly for each job/jail root. That worked fine in small-scale testing. In a wider deployment, however, disaster ensued. With a few thousand mounts, we started to observe two separate forms of bad behavior: - requests from established sessions would hang indefinitely leading to processes backlogging and client machines going OOM and becoming unresponsive en masse. - the NFS server appeared to be serving empty directories. The first one is self-explanatory. The second one might bear further explanation. The server runs ZFS. There are several datasets that contain job roots. E.g.: tank tank/roots tank/roots/a tank/roots/b tank/roots/c tank/roots/d The /etc/exports looks like: V4: /tank -sec=sys For client machines using nullfs, there is an /etc/fstab line like: fs:/roots /roots nfs ro,nfsv4,minorversion=2,tcp,nosuid,noatime,nolockd,noresvport,oneopenown 0 0 Under ordinary operation, NFSv4 exports the child datasets correctly. E.g.: $ ls /roots/a bin etc lib net proc sbin usr dev home libexec root tmp var Then a client does: # for a "Type A" job /sbin/mount_nullfs -o ro -o nosuid /roots/a /jobs/(job-uuid) During the failure, I observed: $ ls /roots a b c d $ ls /roots/a $ ls /roots/b $ ls /roots/c $ ls /roots/d I.e., the server appeared to have "forgotten" to descend into the child datasets and behaved as NFSv3 would have done in that situation. The server in question is FreeBSD 14.1-RELEASE-r5. There were no console diagnostics, nothing in dmesg, and negligible visible load (load average below 1.0, nfsd using ~7% of one CPU). The individual client mounts (the ones that were hanging) were a little different, because they would go straight to the subdirectory they want: # for a "Type A" job /sbin/mount_nfs -o tcp,nfsv4,minorversion=2,noatime -o ro -o nosuid -o noresvport fs:/roots/a /jobs/(job-uuid) Once all the client machines were restarted in "nullfs mode" the server returned to normal operation without further intervention, so the server behavior does appear directly related to the number of client NFS mounts. I couldn't exactly measure it at the time of the incident, but I would ballpark it at about 5,000 +/- 2,000 NFS mounts across 28 client machines. FWIW, during the ~48 hour window where we were testing direct NFS instead of nullfs on slowly increasing numbers of machines, no client using direct NFS experienced the kernel panic we're discussing here. (That's without the patch.) Contrast that to 2-3 total panics per day among the machines using nullfs. So it's possible that indirection through nullfs aggravates that particular bug. Alas, based on the above, nullfs seems to be necessary for now. Getting the patch tested & deployed is now top of my list. Thanks!

While recovering from the problems earlier today, this was dominating the syslog on the NFS fileserver. Sep 27 09:02:07 fs kernel: nfsrv_cache_session: no session IPaddr=10.0.0.8, check NFS clients for unique /etc/hostid's Sep 27 09:02:38 fs syslogd: last message repeated 31 times Sep 27 09:04:39 fs syslogd: last message repeated 121 times Sep 27 09:14:40 fs syslogd: last message repeated 599 times Sep 27 09:24:41 fs syslogd: last message repeated 599 times Sep 27 09:34:43 fs syslogd: last message repeated 600 times Sep 27 09:44:44 fs syslogd: last message repeated 600 times Sep 27 09:54:45 fs syslogd: last message repeated 600 times Sep 27 10:02:05 fs syslogd: last message repeated 439 times That started during the incident. It looks like it started right about the time I rebooted 10.0.0.8 a second time (to switch it back to "nullfs mode"), with the server logging "last message repeated 600 times" every ten minutes. (I.e., once per second) On the client side, it's spewing this with equal frequency: Sep 27 14:50:01 worker8 kernel: Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's It's just that one client machine out of 28. It happens regardless of whether jobs are run via nullfs or NFS. And I can absolutely guarantee that the /etc/hostid files are unique: $ cluster -p -c job_runners uname -n | wc -l 28 $ cluster -p -c job_runners cat /etc/hostid | sort -u | wc -l 28 $ cluster -p -c job_runners sysctl kern.hostid | sort -u | wc -l 28 This continued happening every second, even hours after the incident. Everything else appeared to be running normally. I spared that machine out of the cluster, waited for it to quiesce, and then manually unmounted its NFS mount to the server. Even so, these messages continued to generate on both client and server. Finally, I halted the client machine. It kept at it all the way down: Uptime: 3h56m13s Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's Initiate recovery. If server has not rebooted, check NFS clients for unique /etc/hostid's uhub0: detached acpi0: Powering system off The messages stopped on the server after that, and did not reoccur once I restarted it and returned it to service. I don't know what's up with that, but it seems strange. Possibly something related to rebooting twice (~30 min apart) during a situation where not everything was working properly put NFS on that client machine into an unhappy state?
