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

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

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

On Solaris x86, does zpool (or anything) support PATA (or SATA) IDE SMART data? With the Predictive Self Healing feature, I assumed that Solaris would have at least some SMART support, but what I''ve googled so far has been discouraging. http://prefetch.net/blog/index.php/2006/10/29/solaris-needs-smart-support-please-help/ Bug ID: 4665068 SMART support in IDE driver

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

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

Today I attempted to upgrade to S10_U2 and migrate some mirrored UFS SVM partitions to ZFS. I used Live Upgrade to migrate from U1 to U2 and that went without a hitch on my SunBlade 2000. And the initial conversion of one side of the UFS mirrors to a ZFS pool and subsequent data migration went fine. However, when I attempted to attach the second side mirrors as a mirror of the ZFS pool, all

Tonight I''ve been moving some of my personal data around on my desktop system and have hit some on-disk corruption. As you may know, I''m cursed, and so this had a high probability of ending badly. I have two SCSI disks and use live upgrade, and I have a partition, /aux0, where I tend to keep personal stuff. This is on an SB2500 running snv_46. The upshot is that I have a slice

IHAC that is asking the following. any thoughts would be appreciated Take two drives, zpool to make a mirror. Remove a drive - and the server HANGS. Power off and reboot the server, and everything comes up cleanly. Take the same two drives (still Solaris 10). Install Veritas Volume Manager (4.1). Mirror the two drives. Remove a drive - everything is still running. Replace the drive, everything

In the process of tar''ing up files in an older ZFS partition (23.6.2005), the tar command seized up. Truss showed it hanging in stat64(), so I went looking for symptoms. In "zpool status -ve", I found "4" in the SUM column. Being from the old school, I did "dmesg", expecting to see some kernel error message about the disk but found nothing. Is there

Hi, We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe. Each disk (of 4) is divided up like this / 6GB UFS s0 Swap 8GB s1 /var 6GB UFS s3 Metadb 50MB UFS s4 /data 48GB ZFS s5 For SVM we do a 4 way mirror on /,swap, and /var So we have 3 SVM mirrors d0=root (sub mirrors d10, d20, d30, d40) d1=swap (sub mirrors d11, d21,d31,d41)

Hi, guys, I have add devid support for EFI, (not putback yet) and test it with a zfs mirror, now the mirror can recover even a usb harddisk is unplugged and replugged into a different usb port. But there is still something need to improve. I''m far from zfs expert, correct me if I''m wrong. First, zfs should sense the hotplug event. I use zfs status to check the status of the

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

Hi all, yesterday we had a drive failure on a fc-al jbod with 14 drives. Suddenly the zpool using that jbod stopped to respond to I/O requests and we get tons of the following messages on /var/adm/messages: Sep 3 15:20:10 fb2 scsi: [ID 107833 kern.warning] WARNING: /scsi_vhci/disk at g20000004cfd81b9f (sd52): Sep 3 15:20:10 fb2 SCSI transport failed: reason ''timeout'':

I build two zfs filesystems using b29 (from brandz). I then re-installed solaris express b28, preserving the zfs filesystems. When I tried to "zpool import" my zfs filesystems I got a kernel panic: > debugging crash dump vmcore.0 (32-bit) from blackbird > operating system: 5.11 snv_28 (i86pc) > panic message: > ZFS: bad checksum (read on /dev/dsk/c1d0p0 off 24d5e000: zio

Hello, What is the access algorithm used within multi-component pools for a given pool, and does it change when one or more members of the pool become degraded ? examples: zpool create mtank mirror c1t0d0 c2t0d0 mirror c3t0d0 c4t0d0 mirror c5t0d0 c6t0d0 or; zpool create ztank raidz c1t0d0 c2t0d0 c3t0d0 raidz c4t0d0 c5t0d0 c6t0d0 As files are created on the filesystem within these pools,

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP.
