I have a mirrored ZFS array on a FreeBSD that I used for home NAS, consisting of a 6TB internal drive and a 8TB external USB drive. I have 2TB of space occupied that should not be occupied, but I cannot delete or even see any of its contents. To sum: I have ~2TB of inaccessible space in each pool, space I think corresponds to a never-completed transfer of data. In other words, zfs_bk takes up 5.27 TB, but should be taking up only ~3 TB. However, there are no files in /zfs_bk; the only actual files that can be seen are in the datasets mounted in the subfolders of zfs_bk. Those datasets have sizes consistent with what is contained/displayed in their mountpoints, however. I suspect that this originated when I was transferring a lot of relatively large (>=10GB) files when I was initially setting up my ZFS array (a la send/receive snapshot), but kept getting the infamous broken pipe error when it was almost completed, and so it never finished. If so, how do I delete space referred to by a snapshot? Here is my output: Code: # zfs list NAME USED AVAIL REFER MOUNTPOINT zfs_bk 5.27T 612K 2.28T /zfs_bk zfs_bk/docs 1.23M 612K 1.23M /zfs_bk/me/docs zfs_bk/me 12.1G 612K 8.38G /zfs_bk/me zfs_bk/me/code 209M 612K 209M /zfs_bk/me/code zfs_bk/me/files 77.2M 612K 77.2M /zfs_bk/me/files zfs_bk/me/pictures 2.11G 612K 2.11G /zfs_bk/me/pictures zfs_bk/me/robo 1.29G 612K 1.29G /zfs_bk/me/robo zfs_bk/me/video 88K 612K 88K /zfs_bk/me/video zfs_bk/shared 369G 612K 88K /zfs_bk/shared zfs_bk/shared/images 2.10G 612K 2.10G /zfs_bk/shared/images zfs_bk/shared/music 367G 612K 367G /zfs_bk/shared/music zfs_bk/shared/video 88K 612K 88K /zfs_bk/shared/video zfs_bk/unsorted 2.61T 612K 2.61T /zfs_bk/unsorted zroot 6.18G 101G 88K /zroot zroot/ROOT 2.59G 101G 88K none zroot/ROOT/default 2.59G 101G 2.59G / zroot/tmp 88K 101G 88K /tmp zroot/usr 3.58G 101G 88K /usr zroot/usr/home 641M 101G 641M /usr/home zroot/usr/ports 2.29G 101G 2.29G /usr/ports zroot/usr/src 682M 101G 682M /usr/src zroot/var 1.16M 101G 88K /var zroot/var/audit 88K 101G 88K /var/audit zroot/var/crash 88K 101G 88K /var/crash zroot/var/log 736K 101G 736K /var/log zroot/var/mail 88K 101G 88K /var/mail zroot/var/tmp 96K 101G 96K /var/tmp Code: # ls -a /zfs_bk . .. me shared unsorted Code: # du -h -d=1 /zfs_bk 3.0T /zfs_bk Thanks in advance for any help anyone can offer
It says that I have 2.28 TB used by the root dataset /zfs_bk itself. But how do I free this space? /zfs_bk is completely empty Code: # sudo zfs list -o space -r zfs_bk NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD zfs_bk 436K 5.27T 0 2.28T 0 2.98T zfs_bk/docs 436K 1.23M 0 1.23M 0 0 zfs_bk/me 436K 12.1G 0 8.38G 0 3.68G zfs_bk/me/code 436K 209M 0 209M 0 0 zfs_bk/me/files 436K 77.2M 0 77.2M 0 0 zfs_bk/me/pictures 436K 2.11G 0 2.11G 0 0 zfs_bk/me/robotics 436K 1.29G 0 1.29G 0 0 zfs_bk/me/video 436K 88K 0 88K 0 0 zfs_bk/shared 436K 369G 0 88K 0 369G zfs_bk/shared/images 436K 2.10G 0 2.10G 0 0 zfs_bk/shared/music 436K 367G 0 367G 0 0 zfs_bk/shared/video 436K 88K 0 88K 0 0 zfs_bk/unsorted 436K 2.61T 0 2.61T 0 0
Could I export all of the sub-pools (me, shared, unsorted), delete zfs_bk, remake it and then import the sub-pools? Or something similar?
