https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204764 Bug ID: 204764 Summary: Filesystem deadlock, process in vodead state Product: Base System Version: 10.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: rs@bytecamp.net Created attachment 163453 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=163453&action=edit procstat -kk -a output FreeBSD 10.2-RELEASE-p5 r289218 Deadlock is on an SSD-only mirrored ZFS pool: home ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gpt/mirror0-a ONLINE 0 0 0 gpt/mirror0-b ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 gpt/mirror1-a ONLINE 0 0 0 gpt/mirror1-b ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 gpt/mirror2-a ONLINE 0 0 0 gpt/mirror2-b ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 gpt/mirror3-a ONLINE 0 0 0 gpt/mirror3-b ONLINE 0 0 0 The deadlocked process is a chksetuid run from periodic. The affected directory is identified. Here is a procstat -kk output: 1816 102485 find - mi_switch+0xe1 sleepq_wait+0x3a _sleep+0x287 vnode_create_vobject+0x100 zfs_freebsd_open+0xf5 VOP_OPEN_APV+0xa1 vn_open_vnode+0x234 vn_open_cred+0x33e kern_openat+0x26f amd64_syscall+0x33a Xfast_syscall+0xfb Trying to ls the affected directory ends up in the same: 71376 102400 ls - mi_switch+0xe1 sleepq_wait+0x3a _sleep+0x287 vnode_create_vobject+0x100 zfs_freebsd_open+0xf5 VOP_OPEN_APV+0xa1 vn_open_vnode+0x234 vn_open_cred+0x33e kern_openat+0x26f amd64_syscall+0x33a Xfast_syscall+0xfb However, I'm able to list directory entries via zdb(8). The processes are not killable. The machine is running and non-productive, so I'm able to give any debugging information, just give me some pointers. Attached is the output from procstat -a -kk. -- You are receiving this mail because: You are the assignee for the bug.
