Oh, you're right! Well, that will simplify things! All we have to do
is convince a few bits of code to ignore ub_txg == 0. I'll try a
couple of things and get back to you in a few hours...

Hi List,
First of all: S10u4 120011-14
So I have the weird situation. Earlier this week, I finally mirrored up
two iSCSI based pools. I had been wanting to do this for some time,
because the availability of the data in these pools is important. One
pool mirrored just fine, but the other
It's OK that you're missing labels 2 and 3 -- there are four copies
precisely so that you can afford to lose a few. Labels 2 and 3
are at the end of the disk. The fact that only they are missing
makes me wonder if someone resized the LUNs. Growing them would
be OK, but shrinking them would
Looking at the txg numbers, it's clear that labels on to devices that

Actually, they look OK. The txg values in the label indicate the
last txg in which the pool configuration changed for devices in that
top-level vdev (e.g. mirror or raid-z group), not the
OK, here you go. I've successfully recovered a pool from a detached
device using the attached binary. You can verify its integrity
against the following MD5 hash:
# md5sum labelfix
ab4f33d99fdb48d9d20ee62b49f11e20 labelfix
It takes just one argument -- the disk to repair:
# ./labelfix
Well, 3510 is even supported as JBOD by Sun. The only
limitation is to
use only one FC link.
I have tried both 3510 and 3511 as JBODS - 3510 works
fins, with 3511
I had some problems under higher load.

Hi Robert,
I saw in your post that you had problems

Hi...
Here's my system:

No separate ZIL or ARC cache
ran into a problem today where the ZFS pool jammed

Because this system was in production I had to fairly quickly recover, so I was
unable to play much more with it we had to destroy it and recreate new pool and
then recover data from tapes.
Its a mistery as to why in the middle of a night it rebooted, we could not
figure this out and why pool
Well, thanks your program, I could recover the data on the detach disk. Now I m
copying the data on other disks and resilver it inside the pool.
Warm words aren't enough to express how I feel. This community is great. Thanks
you very much.
