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

Hi experts, I have few issues about ZFS and virtualization: [b]Virtualization and performance[/b] When filesystem traffic occurs on a zpool containing only spindles dedicated to this zpool i/o can be distributed evenly. When the zpool is located on a lun sliced from a raid group shared by multiple systems the capability of doing i/o from this zpool will be limited. Avoiding or limiting i/o to

Hi. I installed solaris express developer edition (b79) on a supermicro quad-core harpertown E5405 with 8 GB ram and two internal sata-drives. I installed solaris onto one of the internal drives. I added an areca arc-1680 sas-controller and configured it in jbod-mode. I attached an external sas-cabinet with 16 sas-drives 1 TB (931 binary GB). I created a raidz2-pool with ten disks and one spare.

I figure this group will know better than any other I have contact with, is 700-800 I/Ops reasonable for a 7200 RPM SATA drive (1 TB Sun badged Seagate ST31000N in a J4400) ? I have a resilver running and am seeing about 700-800 writes/sec. on the hot spare as it resilvers. There is no other I/O activity on this box, as this is a remote replication target for production data. I have a the

As mentioned last night, we''ve been reviewing a proposal for hot spare support in ZFS. Below you can find a current draft of the proposed interfaces. This has not yet been submitted for ARC review, but comments are welcome. Note that this does not include any enhanced FMA diagnosis to determine when a device is "faulted". This will come in a follow-on project, of which some

Hi All, Its been a while since I touched zfs. Is the below still the case with zfs and hardware raid array? Do we still need to provide two luns from the hardware raid then zfs mirror those two luns? http://www.opensolaris.org/os/community/zfs/faq/#hardwareraid Thanks, Shawn -- This message posted from opensolaris.org

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, once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones. Thanks, budy -- This message posted from opensolaris.org

Hi, I had 2 luns in a zfs mirrored config. I increased the size of both the luns by x gig and offlined/online the individual luns in the zpool, also tried an export/import of the zpool, but i am unable to see the increased size....what would i need to do to see the increased size?...or is it not possible yet?

Hi, I do have a disk array that is providing striped LUNs to my Solaris box. Hence I''d like to simply concat those LUNs without adding another layer of striping. Is this possibile with ZFS? As far as I understood, if I use zpool create myPool lun-1 lun-2 ... lun-n I will get a RAID0 striping where each data block is split across all "n" LUNs. If that''s

Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,

Just look at this. I thought all the restarting resilver bugs were fixed, but it looks like something odd is still happening at the start: Status immediately after starting resilver: # zpool status pool: rc-pool state: DEGRADED status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine

We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode....), so we decided to create a whole bunch of

I would like to pick the brains of the ZFS experts on this list: What would you do next to try and recover this zfs pool? I have a ZFS RAIDZ1 pool named bank0 that I cannot import. It was composed of 4 1.5 TiB disks. One disk is totally dead. Another had SMART errors, but using GNU ddrescue I was able to copy all the data off successfully. I have copied all 3 remaining disks as images using

We have a situation where all of the spares in a set of pools have gone into a faulted state and now, apparently, we can''t remove them or otherwise de-fault them. I''m confidant that the underlying disks are fine, but ZFS seems quite unwilling to do anything with the spares situation. (The specific faulted state is ''FAULTED corrupted data'' in ''zpool

Suppose that you have a SAN environment with a lot of LUNs. In the normal course of events this means that ''zpool import'' is very slow, because it has to probe all of the LUNs all of the time. In S10U6, the theoretical ''obvious'' way to get around this for your SAN filesystems seems to be to use a non-default cachefile (likely one cachefile per virtual

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

Good morning, I have a problem with ZFS: ZFS filesystem version 4 ZFS storage pool version 15 Yesterday my comp with Freebsd 8.2 releng shutdown with ad4 error detached,when I copy a big file... and after reboot in 2 wd green 1tb say me goodbye. One of them die and other with zfs errors: Apr 24 04:53:41 Flash root: ZFS: vdev I/O failure, zpool=zroot path= offset=187921768448 size=512 error=6

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

Hi experts zpool import shows some weird config of an old zpool bash-3.00# zpool import pool: data1 id: 7539031628606861598 state: FAULTED status: One or more devices are missing from the system. action: The pool cannot be imported.
