Hi, We are seeing more long delays in zpool import, say, 4~5 or even 25~30 minutes, especially when backup jobs are going on in the FC SAN the LUNs resides (no iSCSI LUNs yet). On the same node for the LUNs of the same array, some pools takes a few seconds, but minutes for some. the pattern seems random to me so far. It''s first noticed soon after being upgraded to Solaris 10 U6

We''re planning to build a ZFS-based Solaris NFS fileserver environment with the backend storage being iSCSI-based, in part because of the possibilities for failover. In exploring things in our test environment, I have noticed that ''zpool import'' takes a fairly long time; about 35 to 45 seconds per pool. A pool import time this slow obviously has implications for how fast

Hello SUN gurus I do not know if this is supported, I have a created a zpool consisting of the SAN resources and created a zfs file system. Using third part software I have taken snapshots of all luns in the zfs pool. My question is in a recovery situation is there a way for me to mount the snapshots and import the pool while the original is still active. Right now all I am able to do is export

I''ve got a server that freezes when I run a zpool scrub from cron. Zpool scrub runs fine from the command line, no errors. The freeze happens within 30 seconds of the zpool scrub happening. The one core dump I succeeded in taking showed an arccache eating up all the ram. The server''s running Solaris 10 u3, kernel patch 127727-11 but it''s been patched and seems to have

I have an OpenSolaris snv_101 box with ZFS on it. (Sun Ultra 20 M2) zpool name is rpool. The I have a 2nd hard drive in the box that I am trying to recover the ZFS data from (long story but that HD became unbootable after installing IPS on the machine) Both drives have a pool named "rpool", so I can''t import the rpool from the 2nd drive. root at hyperion:~# zpool status

Hi, I just found out that ZFS triggers a kernel-panic while switching a mounted volume into read-only mode: The system is attached to a Symmetrix, all zfs-io goes through Powerpath: I ran some io-intensive stuff on /tank/foo and switched the device into read-only mode at the same time (symrdf -g bar failover -establish). ZFS went ''bam'' and triggered a Panic: WARNING: /pci at

I noted this PSARC thread with interest: Re: zpool autoexpand property [PSARC/2008/353 Self Review] because it so happens that during a recent disk upgrade, on a laptop. I''ve migrated a zpool off of one partition onto a slightly larger one, and I''d like to somehow tell zfs to grow the zpool to fill the new partition. So, what''s the best way to do this? (and is it

I''m building a system with two Apple RAIDs attached. I have hardware RAID5 configured so no RAIDZ or RAIDZ2, just a basic zpool pointing at the four LUNs representing the four RAID controllers. For on-going maintenance, will a zpool scrub be of any benefit? From what I''ve read with this layer of abstration ZFS is only maintaining the metadata and not the actual data on the

Hello, We had a situation at customer site where one of the zpool complains about missing devices. We do not know which devices are missing. Here are the details: Customer had a zpool created on a hardware raid(SAN). There is no redundancy in the pool. Pool had 13 LUN''s, customer wanted to increase the size of and added 5 more Luns. During zpool add process system paniced with zfs

Hi, I have just recovered from a ZFS crash. During the antagonizing time this took, I was surprised to learn how undocumented the tools and options for ZFS recovery we''re. I managed to recover thanks to some great forum posts from Victor Latushkin, however without his posts I would still be crying at night... I think the worst example is the zdb man page, which all it does is to ask you

Hi, How I can I quiesce / freeze all writes to zfs and zpool if want to take hardware level snapshots or array snapshot of all devices under a pool ? are there any commands or ioctls or apis available ? Thanks & Regards, sridhar. -- This message posted from opensolaris.org

Hi, I''m struggling to get a stable ZFS replication using Solaris 10 110/06 (actual patches) and AVS 4.0 for several weeks now. We tried it on VMware first and ended up in kernel panics en masse (yes, we read Jim Dunham''s blog articles :-). Now we try on the real thing, two X4500 servers. Well, I have no trouble replicating our kernel panics there, too ... but I think I

Hello, Is it possible to non-destructively change RAID types in zpool while the data remains on-line? -J

Hi, There seems to be a few threads about zpool hang, do we have a workaround to resolve the hang issue without rebooting ? In my case, I have a pool with disks from external LUNs via a fiber cable. When the cable is unplugged while there is IO in the pool, All zpool related command hang (zpool status, zpool list, etc.), put the cable back does not solve the problem. Eventually, I

My server runs S10u5. All slices are UFS. I run a couple of sparse zones on a seperate slice mounted on /zones. When S10u6 comes out booting of ZFS will become possible. That is great news. However, will it be possible to have those zones I run now too? I always understood ZFS and root zones are difficult. I hope to be able to change all FS to ZFS, including the space for the sparse zones. Does

I have a x4540 with a single pool made from a bunch of raidz1''s with 2 spares (solaris 10 u7). Been running great for over a year, but I''ve had my first event. A day ago the system activated one of the spares c4t7d0, but given the status below, I''m not sure what to do next. # zpool status pool: pool1 state: ONLINE scrub: resilver completed after 2h25m

I''ve got 12Gb or so of db+web in a zone on a ZFS filesystem on a mirrored zpool. Noticed during some performance testing today that its i/o bound but using hardly any CPU, so I thought turning on compression would be a quick win. I know I''ll have to copy files for existing data to be compressed, so I was going to make a new filesystem, enable compression and rysnc everything in,
