Re: [zfs-discuss] Steps to Recover a ZFS pool.
I ran into the same thing where I had to manually delete directories. Once you export the pool you can plug in the drives anywhere else. Reimport the pool and the file systems come right up — as long as the drives can be seen by the system. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Moved disks to new controller - cannot import pool even after moving ba
I have moved drives between controllers, rearranged drives in other slots, and moved disk sets between different machines and I've never had an issue with a zpool not importing. Are you sure you didn't remove the drives while the system was powered up? Try this: zpool import -D If zpool lists the pool as destroyed, you can re-import it by doing this: zpool import -D vault I know this is a shot in the dark — sorry for not having a better idea. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Hard drives for ZFS NAS
I use the RE4's at work on the storage server, but at home I use the consumer 1TB green drives. My system [2009.06] uses an Intel Atom 330 based motherboard, 4 gigs of non-ecc ram, a Supermicro AOC-SAT2-MV8 controller with 5 1TB Western Digital [WD10EARS] drives in a raidz1. There are many reasons why this set-up isn't optimal, but in the nine months it's been online, it hasn't produced a single error. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Zpool errors
I had a problems with a UFS file system on a hardware raid controller. It was spitting out errors like crazy, so I rsynced it to a ZFS volume on the same machine. There were a lot of read errors during the transfer and the RAID controller alarm was going off constantly. Rsync was copying the corrupted files to the ZFS volume, and performing a zpool status -v reported the full path name of the affected files. Sometimes only an inode number appears instead of a file path. Is there any way to figure out exactly what files were affected with these inodes? disk_old/some/path/to/a/file disk_old:0x41229e disk_old:0x4124bf disk_old:0x4126a4 disk_old:0x41276f -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] In iSCSI hell...
are you using comstar or the old iSCSI target (iscsitadm) to provision targets? I'm using zfs set shareiscsi=on to confugure the logical units and COMSTAR for the rest on the OpenSolaris side. The targets are initiated on Solaris 10 with iscsiadm. This thing was humming right along and all of a sudden it stopped working after a few weeks. The connection is made via gigabit crossover cable using the e1000g driver on both ends.

[zfs-discuss] In iSCSI hell...
I have a storage server with snv_134 installed. This has four zfs file systems shared with iscsi that are mounted as zfs volumes on a Sun v480. Everything has been working great for about a month, and all of a sudden the v480 has timeout errors when trying to connect to the iscsi volumes on the storage server. The connection between the two is a gigabit crossover cable, so other network traffic isn't an issue. HBAs, NICs, and cables in the storage server have been troubleshot and are working normally. The only common element here is the Intel nic in the v480. It seems to work OK otherwise, but it's the only component in this equation that hasn't changed. What's the consensus on NIC configurations for iscsi? Are errors like this common if the MTU is set at the default of 1500? Any and all comments/opinions are welcome. Thanks. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Zpool hosed during testing

I was able to get Netatalk built on OpenSolaris for my ZFS NAS at home. Everything is running great so far, and I'm planning on using it on the 96TB NAS I'm building for my office.

[zfs-discuss] Using consumer drives in a zraid2
I'm putting together a 48 bay NAS for my company [24 drives to start]. My manager has already ordered 24 2TB [b]WD Caviar Green[/b] consumer drives - should we send these back and order the 2TB [b]WD RE4-GP[/b] enterprise drives instead? I'm tempted to try these out. First off, they're about $100 less per drive. Second, my experience with so called consumer drives in a raid controller has been pretty good - only 2 drive failures in five years with an Apple X-Raid. Thoughts? Opinions? Flames?

[zfs-discuss] ZFS configuration input needed.
I'm in the process of setting up a NAS for my company. It's going to be based on Open Solaris and ZFS, running on a Dell R710 with two SAS 5/E HBAs. Each HBA will be connected to a 24 bay Supermicro JBOD chassis. Each chassis will have 12 drives to start out with, giving us room for expansion as needed. Ideally, I'd like to have a mirror of a raidz2 setup, but from the documentation I've read, it looks like I can't do that, and that a stripe of mirrors is the only way to accomplish this. I'm interested in hearing the opinions of others about the best way to set this up.

Re: [zfs-discuss] ZFS configuration input needed.
You'll have to add a bit of meat to this! What are you resiliency, space and performance requirements? Resiliency is most important, followed by space and then speed. It's primary function is to host digital assets for ad agencies and backups of other servers and workstations in the office. Since I can't make a mirrored raidz2, I'd like the next best thing. If that means doing a zfs send from one raidz2 to the other, that's fine. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
