Hi,
I wrote an hobbit script around lunmap/hbamap commands to monitor SAN health.
I'd like to add detail on what is being hosted by those luns.
With svm metastat -p is helpful.
With zfs, zpool status output is awful for script.
Is there somewhere an utility to show zpool informations in a
Below is my customers issue. I am stuck on this one. I would appreciate
if someone could help me out on this. Thanks in advance!
ZFS Checksum feature:
I/O checksum is one of the main ZFS features; however, there is also
block checksum done by Oracle. This is
good when utilizing UFS since
Hi,
I am new to ZFS and recently managed to get a ZFS root to work.
These were the steps I have done:
1. Installed b81 (fresh install)
2. Unmounted /second_root on c0d0s4
3. Removed /etc/vfstab entry of /second_root
4. Executed ./zfs-actual-root-install.sh c0d0s4
5. Rebooted (init 6)
After
I'm running Postgresql (v8.1.10) on Solaris 10 (Sparc) from within a non-global
zone. I originally had the database storage in the non-global zone (e.g.
/var/local/pgsql/data on a UFS filesystem) and was getting performance of X
(e.g. from a TPC-like application: http://www.tpc.org). I then
Hi all,
Does anyone have any data to show how ZFS raidz with the on-disk cache
enabled for small, random IOs compares to a raid controller card with
cache in raid 5.
I'm working on a very competitive RFP, and one thing that could give us
an advantage is the ability to remove this controller
Does anyone have any particularly creative ZFS replication strategies they
could share?
I have 5 high-performance Cyrus mail-servers, with about a Terabyte of storage
each of which only 200-300 gigs is used though even including 14 days of
snapshot space.
I am thinking about setting up a

Ideally I'd love it if ZFS directly supported the idea of rolling
snapshots out into slower secondary storage disks on the SAN, but in
the meanwhile looks like we have to roll our own solutions.

and AVS is nicely integrated via management RPC interface which is
connecting multiple NexentaStor nodes together and greatly simplifies
AVS usage with ZFS... See demo here:

Hi all
we consider using ZFS for various storages (DB, etc). Most features are great,
especially the ease of use.
Nevertheless, a few questions :
- we are using SAN disks, so most JBOD recommandations dont apply, but I did
not find many experiences of zpool of a few terabytes on Luns... anybody

For small random I/O operations I would expect a substantial performance
penalty for ZFS. The reason is that RAID-Z is more akin to RAID-3 than RAID-5;
each read and write operation touches all of the drives. RAID-5 allows multiple
I/O operations to proceed in parallel since each read and write
