Re: [zfs-discuss] remove snapshots
Hey, "zfs destroy snapshotname" is the way I use to remove snapshots.

Re: [zfs-discuss] Re: Making 'zfs destroy' safer
Actually, if your zfs filesystem has snapshots zfs will complain that the fs can't be destroyed (or that you have to use the -f switch to force it). So the first thing I do when making a new filesystem is create a snapshot to protect me from destroying a filesystem :) On 5/21/07, Peter Schuller <[EMAIL PROTECTED]> wrote: > On the other hand personally I just don't see the need for this since > the @ char isn't special to the shell so I don't see where the original > problem came from. I never actually *had* a problem, I am just nervous about it. And yes, @ is not special for classical shells, but it's still more special than alphanumerics or '/', and probably more likely to *be* special in some languages/alternate shells. Then there is the seemingly trivial issue of the physical keyboard layout. The most common layout will tend to make you use the right shift key in order to type the @, in a particular sequence such that a slight slip of the finger there and *kaboom*, you have lost your (and/or everybody else's) data by accidentally hitting enter instead of shift. One can of course protect against this by writing commands backwards and such, which is what I do for cases like this along with SQL DELETE statements, but to me it just feels unnecessarily dangerous. > One thing that might help here, when not running as root or as a user > with "ZFS File System Management" RBAC profile, is user delegation.

On the other than a very minor modification to the command line tool gets you a pretty significant payoff without complicating things. It will affect the safety of the out-of-the-box tool, regardless of the local policy for privilege delegation. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <[EMAIL PROTECTED]>' Key retrieval: Send an E-Mail to [EMAIL PROTECTED] E-Mail: [EMAIL PROTECTED] Web: http://www.scode.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Re: New zfs pr0n server :)))
About sata controllers, anyone tried http://www.promise.com/product/product_detail_eng.asp?segment=Non-RAID%20HBAs&product_id=139#? It sells here for like 90euro so would be a cheap way for me to add some extra harddrives for a personal zfs server.

Re: [zfs-discuss] Clear corrupted data
Hey, Using the steps on http://www.opensolaris.org/jive/thread.jspa?messageID=39450&tstart=0confirms that it's the iso file. Removing the file does work, I'll just download the file again and let a scrub clean up the error message.

Can you just remove the file or does that error out? If you can upgrade your bits, then 'zpool status -v' will be more informative: http://blogs.sun.com/erickustarz/entry/damaged_files_and_zpool_status From your output, just one block is corrupted (blkid 1919). eric ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Clear corrupted data
Hey, I'm currently running on Nexenta alpha 6 and I have some corrupted data in a pool. The output from sudo zpool status -v data is: pool: data state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: none requested config: NAMESTATE READ WRITE CKSUM dataONLINE 0 010 c2d0 ONLINE 0 0 0 c1d0 ONLINE 0 0 0 c3d0 ONLINE 0 0 0 c4d0 ONLINE 0 0 0 c0d1 ONLINE 0 010 errors: The following persistent errors have been detected: DATASET OBJECT RANGE 1c8 10a5lvl=0 blkid=1919 When accessing the file I'll get an I/O error, is it possible to clear the error and overwrite the corrupted data with all zeroes? I don't know how much data that is corrupted but it's from the Ubuntu 7.04 iso which is downloaded with a torrent and my client hangs at 34% in checking it. If I could just clear the corrupted data the client would pick it up and just redownload that part.
