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
