Hi,
I'm using my pools in perhaps a rather awkward way as underlying storage
for my ceph cluster:
1 disk per pool, with log and cache on SSD
For one reason or another one of the servers has crashed ad does not
really want to read several of the pools:
----
pool: osd_2
state: UNAVAIL
Assertion failed: (reason == ZPOOL_STATUS_OK), file
/usr/src/cddl/contrib/opensolaris/cmd/zpool/zpool_main.c, line 5098.
Abort (core dumped)
----
The code there is like:
----
default:
/*
* The remaining errors can't actually be generated, yet.
*/
assert(reason == ZPOOL_STATUS_OK);
----
And this on already 3 disks.
Running:
FreeBSD 12.1-STABLE (GENERIC) #0 r355208M: Fri Nov 29 10:43:47 CET 2019
Now this is a test cluster, so no harm there in matters of data loss.
And the ceph cluster probably can rebuild everything if I do not lose
too many disk.
But the problem also lies in the fact that not all disk are recognized
by the kernel, and not all disk end up mounted. So I need to remove a
pool first to get more disks online.
Is there anything I can do the get them back online?
Or is this a lost cause?
