Retryable write errors are not fatal, they are retried.

I've got a newly created zpool where I know (from the previous UFS) that one of
the disks has retryable write errors.
What should I do about it now? Just leave zfs to deal with it? Repair it?
If I should repair, if this procedure ok?

I'm running ZFS in a test-server against a bunch of drives in an Apple
XRaid (configured in the JBOD mode). It works pretty well, except that
when I yank one of the drives, ZFS hangs -- presumably, it's waiting
for a response from the the XRAID.
Is there any way to set the device-failure timeout
In a recovery situation where the primary node crashed, the
disks get write-disabled while the failover node takes control.
How can you unmount the zpool? It panics the system and actually
gets into a panic loop when it tries to mount it again on next boot.
Thanks,

Hi,
I've got a 10-disk raidz2 zpool with a dead drive (it's actually been
physically removed from the server pending replacement).
This is how it looks:
# zpool status space
pool: space
state: DEGRADED
status: One or more devices could not be used because the label is
missing or

Wiwat,
You should make sure that you have read the Best Practices Guide and the
Evil Tuning Guide for helpful information on optimizing ZFS for Oracle.
There are some things you can do to tweak ZFS to get better performance
like using a separate filesystem for logs and separating the ZFS inte

While per-dataset scrubbing would certainly be
I implement ZFS with Oracle but it slower than UFS very much. Do you have
any solution?
Can I fix this problem with ZFS direct I/O. If it can, how to set it?

If it's of interest, I've written up some articles on my experiences of
building a ZFS NAS box which you can read here:

I used CIFS to share the filesystems, but it will be a simple matter to use NFS
instead: issue the command 'zfs set
