Hello again,
I am still concerned if my points are being well taken.
If you are concerned that a
single 200TB pool would take a long
time to scrub, then use more pools and scrub in
parallel.
The main concern is not scrub time. Scrub time could be weeks if scrub just
would behave. You may
Sorry if this is too basic -
So I have a single zpool in addition to the rpool, called xpool.
NAMESIZE USED AVAILCAP HEALTH ALTROOT
rpool 136G 109G 27.5G79% ONLINE -
xpool 408G 171G 237G42% ONLINE -
I have 408 in the pool, am using 171 leaving me 237 GB.
Hello,
I'd like to check for any guidance about using zfs on iscsi storage appliances.
Recently I had an unlucky situation with an unlucky storage machine freezing.
Once the storage was up again (rebooted) all other iscsi clients were happy,
while one of the iscsi clients (a sun solaris sparc,
Hi Michael,
For a RAIDZ pool, the zpool list command identifies the inflated space
for the storage pool, which is the physical available space without an
accounting for redundancy overhead.
The zfs list command identifies how much actual pool space is available
to the file systems.
See the
That solved it.
Thank you Cindy.
Zpool list NOT reporting raidz overhead is what threw me...
Thanks again.

Well, I actually don't know what implementation is inside this legacy machine.
This machine is an AMI StoreTrends ITX, but maybe it has been built around IET,
don't know.
Well, maybe I should disable write-back on every zfs host connecting on iscsi?
How do I check this?
Thx
Gabriele.

Hey Scott,
Thanks for the information. I doubt I can drop that kind of cash, but back to
getting bacula working!
Thanks again,

Wow. I never thought about it. I changed the power supply to a cheap one a
while back (a now seemingly foolish effort to save money) - it could be the
issue. I'll change it back and let you know.
Thanks

I understand that L2ARC is still under enhancement. Does any one know if ZFS
can be upgrades to include Persistent L2ARC, ie. L2ARC will not loose its
contents after system reboot ?

hi,
i´m using opensolaris about 2 years with an mirrored rpool and an data pool
with 3 x 2 (mirrored) drives.
the data pool drives are connected to SIL pci-express cards.
yesterday i updated from 130 to 134, everything seemed to be fine and i also
replaced 1 pair of mirrored drives with larger
