I am also experiencing the same problem reported here. In our case virtual machines are backed up to an opensolaris machine via nfs and a script called ghettovcb.sh. The script automatically deletes/rotates old backups. It seems it does delete the files from zfs but zfs is not reclaiming the space. I have no snapshots on the filesystem so are wondering where the space has gone. I removed some files from the opensolaris machine via rm over a ssh session and it deleted the files and reclaimed the space correctly. I'm wondering if this a zfs/nfs share thing?
I have 6+TB of space missing. uname -a SunOS idr-nas-01 5.11 snv_111b i86pc i386 i86pc Solaris # zfs get all VMs/Backups NAME PROPERTY VALUE SOURCE VMs/Backups type filesystem - VMs/Backups creation Wed Dec 2 14:52 2009 - VMs/Backups used 6.18T - VMs/Backups available 38.9G - VMs/Backups referenced 6.18T - VMs/Backups compressratio 1.00x - VMs/Backups mounted yes - VMs/Backups quota none default VMs/Backups reservation none default VMs/Backups recordsize 128K default VMs/Backups mountpoint /export/Backups local VMs/Backups sharenfs r...@xx.xx.xx.160/28,ro...@xx.xx.xx.160/28 local VMs/Backups checksum on default VMs/Backups compression on local VMs/Backups atime on default VMs/Backups devices on default VMs/Backups exec on default VMs/Backups setuid on default VMs/Backups readonly off local VMs/Backups zoned off default VMs/Backups snapdir hidden default VMs/Backups aclmode groupmask default VMs/Backups aclinherit restricted default VMs/Backups canmount on default VMs/Backups shareiscsi off default VMs/Backups xattr on default VMs/Backups copies 1 default VMs/Backups version 3 - VMs/Backups utf8only off - VMs/Backups normalization none - VMs/Backups casesensitivity sensitive - VMs/Backups vscan off default VMs/Backups nbmand off default VMs/Backups sharesmb off default VMs/Backups refquota none default VMs/Backups refreservation none default VMs/Backups primarycache all default VMs/Backups secondarycache all default VMs/Backups usedbysnapshots 0 - VMs/Backups usedbydataset 6.18T - VMs/Backups usedbychildren 0 - VMs/Backups usedbyrefreservation 0 - #df -h /export/Backups Filesystem Size Used Avail Use% Mounted on VMs/Backups 6.3T 6.2T 39G 100% /export/Backups #du -sh /export/Backups/* 1.0K /export/Backups/backup.lst 15K /export/Backups/backup.txt 11G /export/Backups/DR 19K /export/Backups/ghettoVCB.sh 319K /export/Backups/Logs -- This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list storage-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/storage-discuss
