zpool missing

[lidaof]

Dears,

In the issue I reported before, I encountered frequent 'list directory hang' problem of my file system, so I tried some fix by myself. (I think some of the steps might be stupid, and I wish I didn't do that)

I switched to use daily PPA, ran following command:

add-apt-repository ppa:zfs-native/daily
apt-get remove zfs-dkms
apt-get install zfs-dkms ubuntu-zfs

After reboot, my zpool was missing:

zpool status

no pools available

zpool import

failed to read pool configuration: bad address

Then I re-installed zfs support.
apt-get install --reinstall linux-headers-3.2.0-23 linux-headers-3.2.0-23-generic
dkms status
dkms remove -m zfs -v 0.6.2 --all
dkms remove -m spl -v 0.6.2 --all
dkms add -m spl -v 0.6.2
dkms add -m zfs -v 0.6.2
dkms install -m spl -v 0.6.2
dkms install -m zfs -v 0.6.2
dkms status

I am using 0.6.2 zfs:

dkms status

spl, 0.6.2, 3.2.0-23-generic, x86_64: installed
zfs, 0.6.2, 3.2.0-23-generic, x86_64: installed

I am using Ubuntu 12.04:

uname -a

3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

zpool import -D gives no output.
There is no file '/etc/zfs/zpool.cache'

Any solutions? Thanks a lot.

I'm having a simlar problem.

My setup is a gentoo 3.6.11 VM on a VMWare ESXi host. It's been working good since I set it up (except it wouldn't import on start up, had to zpool import -f data).

zpool list

no pools available

zpool import data

cannot import 'data': no such pool available

/etc/init.d/zfs start

This might be due to #2145.

Closing this was very likely caused by #2145
