Heya, > I have/had a zpool containing one filesystem.
Cool, simple scenario. > I had to change my hostid and needed to import my pool, (I've done his > OK in the past). > After the import the mount of my filesystem failed. I take it you did the 'export' part with the other hostid? Wondering if something could have got 'kludged' prior to the host change. > # zpool import homespool > cannot mount 'homespool/homes': mountpoint or dataset is busy What is the path it's being mounted on? Does it exist, is there nothing on it etc? If all else fails you could try a forced unmount with zfs unmount -f homespool/homes . The ZFS developers on this list might cringe at that suggestion though. :) > The data seems it might still exist, (correct amount of used space is > reported), but /homespool > doesn't provide me any obvious way to get to it any more. > # zfs list > NAME USED AVAIL REFER MOUNTPOINT > homespool 9.91G 124G 18K /homespool > homespool/homes 9.91G 124G 9.91G /homes > > ls -laR /homespool <snip> What about ls /homes ? That's the specified mount point and by the looks of the above message the mount hasn't succeeded. When a zfs filesystem has a specified mountpoint outside of the volumes base mount I believe (and there's people on this list who could probably confirm) it disappears from the volume mount. It may add a symlink too (I'm just not sure if that's automatic :)) but since the mount failed it doesn't make sense. > I'd dearly love to recover this pool, (no backup, yes I know :-(. > It WAS a mirror, I scrubbed it and no errors were seen, I've since detached > one device to try to see if anything changed. Well, the good things is you've got the volume mounted. Assuming zpool status homespool returns a good result you should be in luck.
