Re: [zfs-discuss] What to do about retryable write errors?
Oh, it should say retryable and normal write errors - I have permanent errors too /Martin On 2 apr 2008, at 00:55, Richard Elling wrote: Martin Englund wrote: I've got a newly created zpool where I know (from the previous UFS) that one of the disks has retryable write errors.

I'd raise an eyebrow, but otherwise not worry unless there are fatal errors. -- richard If I should repair, if this procedure ok? zpool offline z2 c5t4d0 format -d c5t4d0 repair ... zpool online z2 c5t4d0 cheers, /Martin This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss cheers, /Martin -- Martin Englund, Security Engineer, .Sun Engineering, Sun Microsystems Inc.

[zfs-discuss] zpool DEGRADED after resilver
I replaced a failed disk today, and while the resilvering was running the system crashed. Once the server was back up the resilvering continued, but after it completed it is still in degraded mode: weblogs # zpool status pool: storage state: DEGRADED scrub: resilver completed with 0 errors on Fri Mar 7 15:15:39 2008 config: NAME STATE READ WRITE CKSUM storage DEGRADED 0 0 0 raidz1 DEGRADED 0 0 0 c0t6d0ONLINE 0 0 0 replacing DEGRADED 0 0 0 c1t6d0s0/o UNAVAIL 0 0 0 cannot open c1t6d0 ONLINE 0 0 0 c4t6d0ONLINE 0 0 0 c5t6d0ONLINE 0 0 0 c6t6d0ONLINE 0 0 0 c7t6d0ONLINE 0 0 0 How do I get this back to normal? cheers, /Martin This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] Drobo
Here's another product which has removed the hassle out of disk management: http://www.drobo.com/products_demo.aspx I wonder if they (Data Robotics) will make the Drobo work with ZFS once Leopard is out (since it supports HFS+)? ---8--- Data Robotics has just introduced Drobo, the world’s first storage robot. Drobo is a direct attached storage array that provides fully automated storage that is very easy to use. Drobo attaches via USB 2.0, with no host software required. Drobo combines up to 4 drives (SATA I or III) into a pool of protected storage (i.e. with the protection levels of RAID 5 but with none of the hassles of RAID). Drobo’s capacity can be upgraded on the fly (hot-swappable) with drives of different capacities and speeds, and from different manufacturers. There is a video demonstration of Drobo on www.drobo.com and there are multiple postings about Drobo on the web, including: http://www.engadget.com/2007/04/09/drobo-the-worlds-first-storage-robot/ ---8--- cheers, /Martin -- Martin Englund, Java Security Engineer, Java SE, Sun Microsystems Inc.
