[linux-lvm] Need information

Hi,

I work on cloud platforms and linux. I need some guidance with an issue
observed with LVM.

How to forcefully kill a running lvm command like lvcreate ? I tried using
kill -9 but it is not killing it. Only a reboot seems to does the trick.
How to forcefully kill the lvcreate process or for that matter any running
lvm commands ?

Also how to check the progress of an lvm command like lvcreate or lvremove ?

Thanks
Kumar

Hi

1. lvm2 should not freeze - it would be some horrible bug.

2. You can't kill any userspace app which is blocked in an uninterruptible 
kernel function - kill always wait till it gets to signal handler  (i.e. you 
are opening&reading suspended device might be one such operation)

3. You need to tell us more about what you are doing - as without this there 
is no way to give meaningful help.


Regards

Zdenek

Check `dmsetup udevcookies` output. lvcreate may be waiting for udev
process which timed out - check the syslog. You can forcefully complete a
transaction by `dmsetup udevcomplete <cookie>`
