We have a number of Sun J4200 SAS JBOD arrays which we have multipathed using
Sun's MPxIO facility. While this is great for reliability, it results in the

to be the best of my recollection, I only needed to run zfs scrub, reboot and
the disk became operational again
the irony was that the error message was asking me to recover from backup, but
the disk involved was my backup of my working pool.

Yes. This box has like ten prod zones and ten corresponding zpools
that initiate to iscsi targets on the filers. We can't panic the
whole box just because one {zone/zpool/iscsi target} fails. Are there

Don't forget to change VirtualBox's default cache flush setting.

Hi Daniel,
In some cases, when I/O is suspended, permanent errors are logged and
you need to run a zpool scrub to clear the errors.
Are you saying that a zpool scrub cleared the errors that were
displayed in the zpool status output? Or, did you also use zpool
clear?
Metadata is duplicated even
I already got my files back acctuay and the disc contains already new pools, so
i have no idea how it was set.

Can you please tell me how-to set the failmode?

Some USB disks seem to ignore cache sync requests, w
You can use VCB to backup.
In my test lab, I use VCB integrated with Bacula to backup all the VMs.

Thanks Cindy,
In fact, after some research, I ran into the scrub suggestion and it worked
perfectly. Now I think that the automated message in
http://www.sun.com/msg/ZFS-8000-8A should mention something about scrub as a
worthy attempt.
It was related to an external usb disk. I guess I am happy
I have no idea why this forum just makes files dissapear??? I will put a link
tomorrow...a file was attached before...

Hi guys,
I needed a quick install of OpenSolaris and i found :
http://hub.opensolaris.org/bin/view/Project+jeos/200906+Prototype#HDownloads
The footprint is splendid: around 275 megs, so it is little. But i have a
question.
Why the ZFS and ZPOOL version are that old ?

I encountered the same problem...like i sed in the first post...zpool command
freezes. Anyone knows how to make it respond again?

Hi Daniel,
Unfortunately, the permanent errors are in this pool's metadata so it is
unlikely that this pool can be recovered.
Is this an external USB drive? These drives are not always well-behaved
and its possible that it didn't synchronize successfully.
Is the data accessible? I don't know

backups are for the weak ;-)
