[zfs-discuss] cd into a snapshot using zfs-fuse 0.5.1-1ubuntu5 on Ubuntu 8.10
Hello everybody, Is this the correct list to be talking about zfs-fuse 0.5.1-1ubuntu5 on Ubuntu 8.10? if not, can anyone point me in the right direction? i''ve been googling all morning and i''m at a bit of a loss. else on our solaris machines (running ZFS pool version 10) i can cd into .zfs/snapshot at the root of a zfs file system, ala: cd Backups/natoffice/onsite/.zfs/snapshot. and from there i can cd or ls any of the snapshots to retrieve the data. great. but previously using zfs-fuse (on Ubuntu 8.10), this was not possible. to look at a snapshot we had to clone the snapshot ala: sudo zfs clone zpoolname/zfsname at snapname_somedate zpoolname/zfsname_restore_somedate which works but it''s messy, especially if i don''t know exactly when i need to restore from. So today on Ubuntu 8.10 i received an update to zfs-fuse 0.5.1-1ubuntu5. Now zpool upgrade tells me "This system is currently running ZFS pool version 13." but i still can''t cd into a snapshot. So does a ZFS pool version number mean the same thing between solaris and zfs-fuse, or how different are they really? -- Kind regards, Jules free. open. honest. love. kindness. generosity (Earthcore, 2008)

That, and the inability to use zvol, and the fact that you should create a partition table manually if you''re planning to use entire disk. I believe the complete set is available on the file STATUS. http://www.wizy.org/mercurial/zfs-fuse/trunk/file/008c531499cd/STATUS#l1> > So today on Ubuntu 8.10 i received an update to zfs-fuse > 0.5.1-1ubuntu5. ?Now zpool upgrade tells me "This system is currently > running ZFS pool version 13." > but i still can''t cd into a snapshot. > > So does a ZFS pool version number mean the same thing between solaris > and zfs-fuse, or how different are they really? >zpool and zfs version numbers are the same in (open)solaris, zfs-fuse, *BSD, in the sense that you should be able to import-export properly-created zpools between systems which support the same version. "cd into a snapshot", or to be more accurate ".zfs control directory", is again, a zfs-fuse limitation. Regards, Fajar
