I've been having the same problems, and it appears to be from a remote
monitoring app that calls zpool status and/or zfs list. I've also found
problems with PERC and I'm finally replacing the PERC cards with SAS5/E
controllers (which are much cheaper anyway). Every time I reboot, the PERC

Hi,
I had a hot spare used to replace a failed drive, but then the drive appears to
be fine anyway.
After clearing the error it shows that the drive was resilvered, but keeps the
spare in use.

On some machines running PowerPath, there's sometimes issues after an
update/upgrade of the PowerPath software. Sometimes the pseudo devices get
remapped and change names. ZFS appears to handle it OK, however sometimes it
then references half native device names and half the emcpower pseudo d

The only logs are from subsequent reboots where it says a ZFS pool failed to

I've recently acquired some storage and have been trying to copy data from a
remote data center to hold backup data. The copies had been going for weeks,
with about 600GB transferred so far, and then I noticed the throughput on the
router stopped. I see a pool disappeared.

You may be able to customize it to do direct zfs send/receive, however I find

We have a virtualized environment of T-Series where each host has either zones
or LDoms.
All of the virtual systems will have their own dedicated storage on ZFS (and
some may also get raw LUNs). All the SAN storage is delivered in fixed sized
33GB LUNs.
The question I have to the community i
I recently upgraded a box to Solaris 10 U8.
I've been getting more timeouts and I guess the Adaptec card is suspect, possibly not
able to keep up, so it issues bus resets at times. It has apparently corrupted some
files on the pool, and zpool status -v showed 2 files and one dataset corrupt.
I was frustrated with this problem for months. I've tried different
disks, cables, even disk cabinets. The driver hasn't been updated in
a long time.
When the timeouts occurred, they would freeze for about a minute or
two (showing the 100% busy). I even had the problem with less than 8

Hi,
I'm having trouble with scsi timeouts, but it appears to only happen
when I use ZFS.
I've tried to replicate with SVM, but I can't get the timeouts to happen

ZFS is much better when it does work.
The symptom is tha

Hi,
I was discussing the common practice of disk eradication used by many firms for

to eradicate data as its removed, meaning after the last reference/snapshot is

Is there a way to change the device name used to create a zpool?
My customer created their pool with physical device names rather than
the emc powerpath virtual names.
They have data on there already, so they would like to preserve it.
My experience with zpool replace is that it copies data ove
In a recovery situation where the primary node crashed, the

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.
