[zfs-discuss] How crazy ZFS import command................
Hi All, Today I created a zpool (name as testpool) on c0t0d0. #zpool create -m /masthan testpool c0t0d0 Then I written some data on the pool #cp /usha/* /masthan/ Then I destroyed the zpool #zpool destroy testpool After that I created UFS File System on the same device i.e. on c0t0d0 . #newfs -f 2048 /dev/rdsk/c0t0d0s2 and then I mounted it and i written some data on it ... after that It is unmounted. But still I am able to see ZFS file system on the c0t0d0 the command #zpool import -Df testpool.... Is successfully importing the testpool and it is successfully show all the files what I written earlier Whats wrong with ZFS import command ? On a ZFS disk after creating a new file system also it is recovering old ZFS file system on it . Why ZFS designed like that ? How it is recovering the old ZFS Fs ? -Masthan --------------------------------- Food fight? Enjoy some healthy debate in the Yahoo!

Gino, We have ween this before but only very rarely and never got a good crash dump. Coincidently, we saw it only yesterday on a server here, and are currently investigating it. Did you also get a dump we can access? That would If not can you tell us what zfs version you were running. At the moment I''m not sure how even you can recover from it. Sorry about this problem. FYI this is bug: http://bugs.opensolaris.org/view_bug.do?bug_id=6458218 Neil.

This would occur if /dev/rdsk/c0t0d0s2 is not the same as c0t0d0 Double check your partition table. -- richard dudekula mastan wrote:> Hi All, > > Today I created a zpool (name as testpool) on c0t0d0. > > #zpool create -m /masthan testpool c0t0d0 > > Then I written some data on the pool > > #cp /usha/* /masthan/ > > Then I destroyed the zpool > > #zpool destroy testpool > > After that I created UFS File System on the same device i.e. on c0t0d0 . > > #newfs -f 2048 /dev/rdsk/c0t0d0s2 > and then I mounted it and i written some data on it ... after that It is > unmounted. > > But still I am able to see ZFS file system on the c0t0d0 > > the command #zpool import -Df testpool....
