Re: [zfs-discuss] ZFS snapshot splitting joining

Thanks to John K. and Richard E. for an answer that would have never, ever occurred to me... The problem was with the shell. For whatever reason, /usr/bin/ksh can't rejoin the files correctly. When I switched to /sbin/sh, the rejoin worked fine, the cksum's matched, and the zfs recv worked

Hi again everyone, OK... I'm even more confused at what is happening here when I try to rejoin the split zfs send file... When I cat the split files and pipe through cksum, I get the same cksum as the original (unsplit) zfs send snapshot: #cat mypictures.zfssnap.split.a[a-d] |cksum

Hi everyone, I appreciate the discussion on the practicality of archiving ZFS sends, but right now I don't know of any other options. I'm a home user, so Enterprise-level solutions aren't available and as far as I know, tar, cpio, etc. don't capture ACL's and other low-level filesystem

[zfs-discuss] ZFS snapshot splitting joining

2009-02-04 Thread Michael McKnight
Hello everyone, I am trying to take ZFS snapshots (ie. zfs send) and burn them to DVD's for offsite storage. In many cases, the snapshots greatly exceed the 8GB I can stuff onto a single DVD-DL. In order to make this work, I have used the split utility to break the images into smaller,

Yes, but I can't export a pool that has never been imported. These drives are no longer connected to their original system, and at this point, when I connect them to their original system, the results are the same. Thanks, Michael --- On Tue, 12/30/08, Weldon S Godfrey 3 wel...@excelsus.com

[zfs-discuss] ZFS Import Problem

2008-12-30 Thread Michael McKnight
Hi everyone, I have a serious problem and need some assistance. I was doing a rolling upgrade of a raidz1, replacing 320GB drives with 1.5TB drives (ie. zpool replace). I had replaced three of the drives and they had resilvered without errors and then I started on the fourth one. It went

I'm not an expert but for what it's worth- 1. Try the original system. It might be a fluke/bad cable or anything else intermittent. I've seen it happen here. If so, your pool may be alright. 2. For the (defunct) originals, I'd say we'd need to take a look into the sources to find if

[zfs-discuss] Suggestion/Request: ZFS-aware rm command

2007-11-07 Thread Michael McKnight
Hello again, Some of you may have read my earlier post about wanting to recover partial ZFS space. It seems as though that isn't possible given the current implementation... so, I would like to suggest the following enhancement: A zfs-aware rm command (ie. zfs rm). The idea here is that we

[zfs-discuss] Partial ZFS Space Recovery

2007-11-06 Thread Michael McKnight
Hi everyone, I have what I think is a simple question, but the answer is eluding me... I have a ZFS filesystem in which I needed to move part of it to a new pool. I want to recover the space from the part I moved so that it returns to the original pool, without losing the snapshot data of the
