#60 — zpool import doesn't mount anything

Hi, sorry I shouldn't have bothered with zfs mount -a at all at this point. If I focus on zpool import;

The zpool does import but as I said nothing mounts and although I can set mountpoints to legacy I'm unsure how I can mount then manually. The mountpoints that are needed are created by zpool import though.

shadow ~ # fusermount -V
fusermount version: 2.8.1

'zpool import -d /dev -d /dev/mapper tank' again imports the tank but still;

shadow ~ # zpool export tank
shadow ~ # zpool import -d /dev/ -d /dev/mapper tank
cannot mount 'tank': Input/output error.
Make sure the FUSE module is loaded.

zpool status -v reports no errors (all the resilvering was completed yesterday without any problems)

The zfs launch script is the one provided in the ebuild and no mention of ulimit. I'll give the 0.6.9 source version a try just in case this is something Gentoo specific.

Cheers,

Hi, please disregard my request. I'm not sure the error msg I got was a feature or a bug but if I start zfs-fuse with;

--no-kstat-mount

then an import tank does correctly mount what is required. This was with the compiled from source version so I shall give it a go with the Gentoo specific one now.

Cheers for the good work people.

Hi, would be glad to help, will post results later when I get home.

I did see some mention of /zfs-kstat in mtab before I rebooted to make sure I had a plain environment for these tests.

No thats fine dude, I can confirm the zpool was indeed imported and the --no-kstat-mount wasn't being used. I'll double check this for you now to be certain.

If this problem is something you want fixed I'd happily try more complex procedures (I'm a Unix sysadmin by trade so know my way around Linux :)). Also if it helps I would be happy to provide ssh access for you to look at the the problem remotely.

Yeah I tried to switch to Debian (for my desktop) but everytime I hit something that didn't work I wasn't sure were anything was and crept back to the comfort of Gentoo (been using it since 02 roughly so know it very well :P).

I have no idea how similar sabayon is but thats the problem with gentoo I guess, what is a "default" install? I do feel sorry for those debugging Gentoo issues since you would need to know so much (think emerge -info is the main one?)

Well when you want to jump on let me know and ill sort you out a login, etc (over PM or email of course lol)
