Re: [zfs-discuss] 700GB gone? zfs list and df differs!
The problem is more clearly stated here. Look, 700GB is gone (the correct number is 620GB)! First I do zfs list onto TempStorage/Backup which reports 800GB. This is correct. Then I do df -h which reports only 180GB, which is not correct. So, it should be 800GB of data, but df reports only 180GB. This means 620GB is gone. Where is it? I know there is 620GB worth of data, which I can not access. Where is my data, and how can I access it? root@solaris:/mnt/TempStorage/Stuff# zfs list NAME USED AVAIL REFER MOUNTPOINT TempStorage 916G 45,1G 37,3G /mnt/TempStorage TempStorage/Backup799G 45,1G 177G /mnt/TempStorage/Backup OBS! 800GB!

Well, close anyway. See http://hub.opensolaris.org/bin/view/Community+Group+zfs/faq/#HWhydoesdu1reportdifferentfilesizesforZFSandUFSWhydoesntthespaceconsumptionthatisreportedbythedfcommandandthezfslistcommandmatch - zfs will show a fake number in df's Size, to be roughly the sum of Used + Avail for that particular filesystem. fake, as in this not the actual pool size. So in short, for filesystem/dataset in the same pool, df will show the same Avail, but different Used and Size. -- Fajar ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You probably have snapshots eating the remaining 620GB... I thought so too - df can lie a bit about used space, but not by such a margin in my experience. It would only report the live dataset, not its snapshots, though. Try running: # zfs list -tall -r TempStorage/Backup If you have some data you can't access now, it is possibly removed (by rm or alike) and referred to in the snapshots, perhaps automatic (like zfs-autosnapshot service or the time slider service). If so, you can access the files under /mnt/TempStorage/Backup/.zfs/snapshots/SNAPSHOTNAME/your/data/path/file HTH, //Jim ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] 700GB gone?
I am using 64bit S11E. Everything worked fine earlier. But now I suspect the disk is breaking down, it behaves weird. I have several partitions: 1) OpenSolaris b134 upgraded to S11E 2) WinXP 3) FAT32 4) ZFS storage pool of 900GB Earlier, everything was fine. But suddenly OpenSolaris does not work anymore. When I boot via GRUB, it gives an error message and halts. I have installed S11E on a new disk, and when I try to import the old rpool 1) then the computer reboots: http://opensolaris.org/jive/thread.jspa?messageID=517089#517089 So there are some problems. My storage pool 4) is suddenly 300GB big and where is the data? I have one snapshot, or so. I have not deleted stuff. I suspect the disk is breaking down. How can I tell? I am scrubbing the disk now, but so far no errors (50% done). Can I examine the disk somehow? Format shows all four partitions. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
