After having to replace an internal raid card in an X2200 (S10U3 in this case), I can see the disks just fine - and can boot, so the data isn''t completely missing. However, my zpool has gone. # zpool status -x pool: storage state: FAULTED status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

A question regarding zfs_nocacheflush: The Evil Tuning Guide says to only enable this if every device is protected by NVRAM. However, is it safe to enable zfs_nocacheflush when I also have local drives (the internal system drives) using ZFS, in particular if the write cache is disabled on those drives? What I have is a local zfs pool from the free space on the internal drives, so I''m

I''m moving some data off an old machine to something reasonably new. Normally, the new machine performs better, but I have one case just now where the new system is terribly slow. Old machine - V880 (Solaris 8) with SVM raid-5: # ptime du -kds foo 15043722 foo real 6.955 user 0.964 sys 5.492 And now the new machine - T5140 (latest Solaris 10) with ZFS

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

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

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

Hello zfs-discuss, Relatively low traffic to the pool but sync takes too long to complete and other operations are also not that fast. Disks are on 3510 array. zil_disable=1. bash-3.00# ptime sync real 1:21.569 user 0.001 sys 0.027 During sync zpool iostat and vmstat look like: f3-1 504G 720G 370 859 995K 10.2M misc 20.6M 52.0G 0 0

Hi, S10U3: It seems, that ufs POSIX-ACLs are not properly translated to zfs ACL4 entries, when one xfers a directory tree from UFS to ZFS. Test case: Assuming one has an user A and B, both belonging to group G and having their umask set to 022: 1) On UFS - as user A do: mkdir /dir chmod 0775 /dir setfacl -m d:u::rwx,d:g::rwx,d:o:r-x,d:m:rwx /dir # samba would

ZFS introduces a new and incompatible ACL interface into Solaris and this seems to be not yet fully completed in addition to the fact that is causes a lot of problems for software that needs to be compatible with Solaris-2.5 like star. Proof for incompatibility: create a file on UFS and set an ACL for this file. Use Sun tar cpf out file to archive this file. Unpack this archive file on ZFS

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, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP. Here is the error message when I try to create my pool: bash-3.00# zpool create tank /dev/dsk/vpath1a warning: device in use checking failed: No such device internal error: unexpected error 22 at line 446 of ../common/libzfs_pool.c bash-3.00# zpool create tank /dev/dsk/vpath1c cannot open

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices. List steps to reproduce the problem(if applicable): Build Solaris 10 Update 2 server Attach to an external

While testing a zpool with a different storage adapter using my "blkdev" device, I did a test which made a disk unavailable -- all attempts to read from it report EIO. I expected my configuration (which is a 3 disk test, with 2 disks in a RAIDZ and a hot spare) to work where the hot spare would automatically be activated. But I''m finding that ZFS does not behave this way

So, my Areca controller has been complaining via email of read errors for a couple days on SATA channel 8. The disk finally gave up last night at 17:40. I got to say I really appreciate the Areca controller taking such good care of me. For some reason, I wasn''t able to log into the server last night or in the morning, probably because my home dir was on the zpool with the failed disk

Folks, How can I find out zpool id without using zpool import? zpool list and zpool status does not have option as of Solaris 10U5.. Any back door to grab this property will be helpful. Thank you Ajay

Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

Hi, If I add an entire disk to a new pool by doing "zpool create", is this reversible? I.e. if there was data on that disk (e.g. it was the sole disk in a zpool in another system) can I get this back or is zpool create destructive? Joubert This message posted from opensolaris.org
