[zfs-discuss] zfs snaps and removing some files
Hello folks, I have strange and unusual request... I have two 300gig drives mirrored: [11:33:22] [EMAIL PROTECTED]: /d/d2 zpool status pool: mypool state: ONLINE scrub: none requested config: NAMESTATE READ WRITE CKSUM mypool ONLINE 0 0 0 mirrorONLINE 0 0 0 c1t2d0 ONLINE 0 0 0 c1t3d0 ONLINE 0 0 0 errors: No known data errors it does give me total of [11:32:55] [EMAIL PROTECTED]: /d/d2 zpool list NAMESIZEUSED AVAILCAP HEALTH ALTROOT mypool 278G271G 6.75G97% ONLINE - I am using around 150 gig of that 278 gig that I have and disk is 99% full [11:33:58] [EMAIL PROTECTED]: /d/d2 df -k .

I did go to snaps and I did try to remove them but I got message: [11:42:50] [EMAIL PROTECTED]: /d/d2/.zfs/snapshot/month_01 rm studio11-sol-sparc.tar rm: remove write-protected file `studio11-sol-sparc.tar'? y rm: cannot unlink `studio11-sol-sparc.tar': Read-only file system [11:43:01] [EMAIL PROTECTED]: /d/d2/.zfs/snapshot/month_01 [11:43:03] [EMAIL PROTECTED]: /d/d2/.zfs/snapshot/month_01 ls -la studio11-sol-sparc.tar -rw-rw-r--1 root root 1123425280 Jan 25 2006 studio11-sol-sparc.tar [11:43:16] [EMAIL PROTECTED]: /d/d2/.zfs/snapshot/month_01 Is there a way to mount file system as read/write and be able to remove those big files that I dont need there? I would love to keep those snaps for months... I know, easy suggestion would be to add more disk space and never worry about it but yet again in my situation I have two internal disks that are 300gb and I cannot add more internal drives to that system so I rather use what I can... Thanks for any help. Chris ___ zfs-discuss mailing list [EMAIL PROTECTED] http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I certainly do understand the design of zfs file system and I was just wondering if what I wanted is possible... so just on that one file example that I had, if I could just go and remove that particular file from every snap like that file would never existed... If I dont do that and I remove it from my file system those references will stay in all snaps except for the last one and that is all great... but my issue at this moment is that I have 300gb drive and only 150gb of disk space used and my file system is at almost 100% Soon I will not be able to take any snaps unless I remove some old ones or add another mirror to it... Anyway just wanted to know if any of that woul dbe possible in any way... Chris, you may want to try cloning these snapshots, removing these big files from the clone and then zfs send/recv these clones, instead of original snapshots. -- Regards, Cyril ___ zfs-discuss mailing list [EMAIL PROTECTED] http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
