The heads have Perc H800 card and drives are configured in Raid0 ( Virtual Disk) in the RAID controller. One of the drives had crashed and is replaced by a spare. Resilvering was triggered but fails to complete due to drives going offline. I have to reboot the head ( R710) and drives comes online. This happened repeatedly when resilver was 4% done, and again was rebooted , again hung at 27% done, etc. The issues happens with both Solaris11.1/ Omnios. Its a 100Tb pool with 69Tb used. I have critical data and cant afford loss of data. Can I recover the data anyway ( atleast partially ) ? I had verified there is no hardware issue with H800 and also upgraded the firmware for H800. The issue happens with both the heads.

My remotely supported home-NAS PC was unavailable for a while, and a friend rebooted it for me from a LiveUSB image with SSH (oi_148a). I can see my main pool disks, but not the old boot (rpool) drive. Meaning, that it does not appear in "zpool import" nor in "format" outputs. While it is possible that it has finally kicked the bucket, and that won't really be unexpected, I'd like to try and confirm. For example, it might fail to spin up or come into contact with the SATA cable initially - but subsequent probing of the same controller might just find it. Happened before, too - though via a reboot and full POST... The friend won't be available for a few days, and there's no other remote management nor inspection facility for this box, so I'd like to probe from within OI as much as I can.

Hardware details at the end of the message. They were running OI 151.a.5 for months. The zpool configuration was one storage zpool with 3 vdevs of 8 disks in RAIDZ2. The OI installation is absolutely clean. Just next-next-next until done. All I do is configure the network after install. I don't install or enable any other services. Then I added more disks and rebuild the systems with OI 151.a.7 and this time configured the zpool with 6 vdevs of 5 disks in RAIDZ. The systems started crashing really bad. They just disappear from the network, black and unresponsive console, no error lights but no activity indication either. The only way out is to power cycle the system. There is no pattern in the crashes. It may crash in 2 days in may crash in 2 hours. I upgraded the memory on both systems to 128GB at no avail. This is the max memory they can take. In summary all I did is upgrade to OI 151.a.7 and reconfigured zpool.

I've been asked to look into this, and was told "low performance" is fine, workload is likely to be write-once, read-occasionally, archive storage of gene sequencing data. Probably a single 10Gbit NIC for connectivity is sufficient. We've had decent success with the 45-slot, 4U SuperMicro SAS disk chassis, using 4TB "nearline SAS" drives, giving over 100TB usable space (raidz3). Back-of-the-envelope might suggest stacking up eight to ten of those, depending if you want a "raw marketing petabyte", or a proper "power-of-two usable petabyte". I get a little nervous at the thought of hooking all that up to a single server, and am a little vague on how much RAM would be advisable, other than "as much as will fit" (:-). Then again, I've been waiting for something like pNFS/NFSv4.1 to be usable for gluing together multiple NFS servers into a single global namespace, without any sign of that happening anytime soon. So, has anyone done this?

My home NAS died over the weekend, and it leaves me with a lot of spare drives (5 2Tb and 3 1Tb disks). I have a Dell Poweredge 2900 Server sitting in the house, which has not been doing much over the last while (bought it a few years back with the intent of using it as a storage box, since it has 8 Hot Swap drive bays) and i am now looking at building the NAS using ZFS... But, now i am confused as to what OS to use... OpenIndiana? Nexenta? FreeNAS/FreeBSD? I need something that will allow me to share files over SMB (3 if possible), NFS, AFP (for Time Machine) and iSCSI. Ideally, i would like something i can manage "easily" and something that works with the Dell... Any recommendations? Any comparisons to each? Thanks. </pre> Tiernan OToole 2013-02-25T14:57:51 http://comments.gmane.org/gmane.os.solaris.opensolaris.zfs/51026 <pre> I have come up against a common problem (Most recently discussed in thread titled "cannot replace X with Y: devices have different sector alignment"), and have to do a " zfs send -R ... | zfs recv ..." to migrate from old to new disks. While searching I saw reference to a new feature being discussed years ago under the title of "RFE 4852783 (need for an equivalent to LVM2's pvmove)" which would have made the process much easier. I'm using mirrored pairs of disks where I could have removed one disk from an old mirror (made up of ashift=9 disks), added a new (ashift=12) single-disk, done this "move/detach", and then added a second new (ashift=12) disk to the new mirror. I can't find any ticket in any current tracking system, so am curious if there is any current discussion of this. Being able to remove vdevs from a pool would make a number of management tasks easier, and avoid the send/recv of entire pools to deal with an issue with a single vdev. Thank you. </pre> Russell McOrmond 2013-02-21T16:15:48 http://comments.gmane.org/gmane.os.solaris.opensolaris.zfs/51025 <pre># zfs list -t vol NAME USED AVAIL REFER MOUNTPOINT rpool/dump 4.00G 99.9G 4.00G - rpool/foo128 66.2M 100G 16K - rpool/swap 4.00G 99.9G 4.00G - # zfs destroy rpool/foo128 cannot destroy 'rpool/foo128': volume is busy I checked that the volume is not a dump or swap device and that iSCSI is disabled.

When I bought my storage servers I intentionally left hdd slots available so I can add another vdev when needed and delay immediate expenses. After reading some posts on the mailing list I'm getting concerned about degrading performance due to unequal distribution of data among the vdevs. I still have a chance to migrate the data away, add all drives and rebuild the pools and start fresh. Before going that road I was hoping to hear your opinion on what will be the best way to handle this.

My name is Markus and I living in germany. I'm new to this list and I have a simple question related to zfs. My favorite operating system is FreeBSD and I'm very happy to use zfs on them. It's possible to enhance the properties in the current source tree with an entry like "protected"? I find it seems not to be difficult but I'm not an professional C programmer. For more information please take a little bit of time and read my short post at http://forums.freebsd.org/showthread.php?t=37895 I have reviewed some pieces of the source code in FreeBSD 9.1 to find out how difficult it was to add an pool / filesystem property as an additional security layer for administrators. Whenever I modify zfs pools or filesystems it's possible to destroy [on a bad day :-)] my data. A new property "protected=on|off" in the pool and/or filesystem can help the administrator for datalost (e.g. "zpool destroy tank" or "zfs destroy &lt;tank/filesystem&gt;" command will be rejected when "protected=on" property is set).

I have a development fileserver box running Solaris 11 Express. The Rpool is mirrored between an SSD and a hard drive. Today, the SSD deveoped a fault for some reason. While trying to diagnose the problem, the system panicked and rebooted. The SSD was the first boot drive, and every time it tried to boot it panicked and rebooted, ending up in a loop. I tried to change to the second rpool drive, but either I forgot to install grub on it or it has become corrupted (probably the first, I can be that stupid at times). Can anyone give me any advice on how to get this system back? Can I trick grub, installed on the SSD, to boot from the HDD's rpool mirror? Is something more sinister going on? By the way, whatever the error message is when booting, it disapears so quickly I can't read it, so I am only guessing that this is the reason. PLEASE HELP!

Have good or bad things to say, in terms of reliability, performance, features? My main reason for asking is this: I have a mac, I use Time Machine, and I have VM's inside. Time Machine, while great in general, has the limitation of being unable to intelligently identify changed bits inside a VM file. So you have to exclude the VM from Time Machine, and you have to run backup software inside the VM. I would greatly prefer, if it's reliable, to let the VM reside on ZFS and use zfs send to backup my guest VM's. I am not looking to replace HFS+ as the primary filesystem of the mac; although that would be cool, there's often a reliability benefit to staying on the supported, beaten path, standard configuration. But if ZFS can be used to hold the guest VM storage reliably, I would benefit from that.
