.. evidently doesn''t work. GRUB reboots the machine moments after loading stage2, and doesn''t recognise the fstype when examining the disk loaded from an alernate source. This is with SX-151. Here''s hoping a future version (with grub2?) resolves this, as well as lets us boot from raidz. Just a note for the archives in case it helps someone else get back the afternoon

I sent a zvol from host a, to host b, twice. Host b has two pools, one ashift=9, one ashift=12. I sent the zvol to each of the pools on b. The original source pool is ashift=9, and an old revision (2009_06 because it''s still running xen). I sent it twice, because something strange happened on the first send, to the ashift=12 pool. "zfs list -o space" showed figures at

I have a Solaris 10 update 6 system with a snapshot I can''t remove. zfs destroy -f <snap> reports the device as being busy. fuser doesn''t shore any process using the filesystem and it isn''t shared. I can unmount the filesystem OK. Any clues or suggestions of bigger sticks to hit it with? -- Ian.

I would like to get some help diagnosing permanent errors on my files. The machine in question has 12 1TB disks connected to an Areca raid card. I installed OpenSolaris build 134 and according to zpool history, created a pool with zpool create bigraid raidz2 c4t0d0 c4t0d1 c4t0d2 c4t0d3 c4t0d4 c4t0d5 c4t0d6 c4t0d7 c4t1d0 c4t1d1 c4t1d2 c4t1d3 I then backed up 806G of files to the machine, and had

FULL backup to a file zfs snapshot -r rpool at 0908 zfs send -Rv rpool at 0908 > /net/remote/rpool/snaps/rpool.0908 INCREMENTAL backup to a file zfs snapshot -i rpool at 0908 rpool at 090822 zfs send -Rv rpool at 090822 > /net/remote/rpool/snaps/rpool.090822 As I understand the latter gives a file with changes between 0908 and 090822. Is this correct? How do I restore those files? I know

Hi, I wanted to add a disk to the tank pool to create a mirror. I accidentally used zpool add ? instead of zpool attach ? and now the disk is added. Is there a way to remove the disk without loosing data? Or maybe change it to mirror? Thanks, Martijn -- This message posted from opensolaris.org

With all the recent discussion of SSD''s that lack suitable power-failure cache protection, surely there''s an opportunity for a separate modular solution? I know there used to be (years and years ago) small internal UPS''s that fit in a few 5.25" drive bays. They were designed to power the motherboard and peripherals, with the advantage of simplicity and efficiency

I''m working with a Cyrus IMAP server running on a T2000 box under Solaris 10 10/09 with current patches. Mailboxes reside on six ZFS filesystems, each containing about 200 gigabytes of data. These are part of a single zpool built on four Iscsi devices from our Netapp filer. One of these ZFS filesystems contains a number of global and per-user databases in addition to one sixth of the

Is there a mechanism by which you can perform a zfs send | zfs receive and not have the data uncompressed and recompressed at the other end? I have a gzip-9 compressed filesystem that I want to backup to a remote system and would prefer not to have to recompress everything again at such great computation expense. If this doesn''t exist, how would one go about creating an RFE for

I have a simple mirror pool with 2 disks. I pulled out one disk to simulate a failed drive. zpool status shows that the pool is in DEGRADED state. I want syslog to log these type of ZFS errors. I have syslog running and logging all sorts of error to a log server. But this failed disk in ZFS pool did not generate any syslog messages.

Hi everyone, Please review the information below regarding access to ZFS version information. Let me know if you have questions.

Hello, Experts. I''ve got a problem. I''m trying to expand my main zpool (rpool), but don''t know how to do that. (i''m 100% newbie in non-windows world) I use Osol under Vmware on Windows. I had a pretty small vhdd -> only 12gb. Yesterday i decided to expand my virtual drive to 20gb. (After several tries to upgrade the OS to a newest dev-releases and

Hi all, just after sending a message to sunmanagers I realized that my question should rather have gone here. So sunmanagers please excus ethe double post: I have inherited a X4140 (8 SAS slots) and have just setup the system with Solaris 10 09. I first setup the system on a mirrored pool over the first two disks pool: rpool state: ONLINE scrub: none requested config: NAME

What is the best way to back up a zfs pool for recovery? Recover entire pool or files from a pool... Would you use snapshots and clones? I would like to move the "backup" to a different disk and not use tapes. suggestions?? TIA --Kenny -- This message posted from opensolaris.org

I have been searching this forum and just about every ZFS document i can find trying to find the answer to my questions. But i believe the answer i am looking for is not going to be documented and is probably best learned from experience. This is my first time playing around with open solaris and ZFS. I am in the midst of replacing my home based filed server. This server hosts all of my media

I''m building another 24-bay rackmount storage server, and I''m considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM drive in both SAS and SATA configurations; the SAS model offers

Can I send a zfs send stream (ZFS pool version 22 ; ZFS filesystem version 4) to a zfs receive stream on Solaris 10 (ZFS pool version 15 ; ZFS filesystem version 4)? -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + http://nagual.nl/ | SunOS 10u7 5/09 | OpenSolaris 2010.03 b131 + All that''s really worth doing is what we do for others (Lewis Carrol)

Its marketing name is: Seagate Expansion 3 TB USB 3.0 Desktop External Hard Drive STAY3000102 format(1M) shows it identify itself as: Seagate-External-SG11-2.73TB Under both Solaris 10 and Solaris 11x, I receive the evil message: | I/O request is not aligned with 4096 disk sector size. | It is handled through Read Modify Write but the performance

I have some questions about the choice of SSDs to use for ZIL and L2ARC. I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system, which is intended to be used as a backup SAN during storage migration, so it''s built on a tight budget. The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII SATA HDDs attached to an Areca 8port ARC-1220 controller

Due to recent experiences, and discussion on this list, my colleague and I performed some tests: Using solaris 10, fully upgraded. (zpool 15 is latest, which does not have log device removal that was introduced in zpool 19) In any way possible, you lose an unmirrored log device, and the OS will crash, and the whole zpool is permanently gone, even after reboots. Using opensolaris,
