Good day!
I'm running OMV 2.2.10, on a Lenovo TS440
So I wanted to expand my RAID Volume, but I didn't realize that it's not possible to change the raid level when expanding (at least not in the GUI). I figured it would be pretty easy to blow away the array and start fresh. So first I backed up all my information I wanted saved, and then decided it was time to start the process. So I did the following:
- I disabled all services in OMV, including SMB and anything else that might have been running.
- Then I went to the RAID configuration page, and went to delete the array, only problem was that the option to delete was greyed out.
No big deal, I figured, I'll do this with mdadm. So I went into MDADM and tried to stop the array and got this back:
mdadm: Cannot get exclusive access to /dev/md1:Perhaps a running process, mounted filesystem or active volume group?
So I decided to boot Linux into single user mode as it seems like a lot of people have run into similar issues. In single user mode, same error. Running lsof | grep md1 returns the following:
root@omv:~# lsof | grep md1
md1_raid1 411 root cwd DIR 8,1 4096 2 /
md1_raid1 411 root rtd DIR 8,1 4096 2 /
md1_raid1 411 root txt unknown /proc/411/exe
jbd2/md1- 1740 root cwd DIR 8,1 4096 2 /
jbd2/md1- 1740 root rtd DIR 8,1 4096 2 /
jbd2/md1- 1740 root txt unknown /proc/1740/exe
I try killing the processes, no go, not even in single user mode.
I feel like I'm at the point of physically removing the drives, popping them in another box, zeroing them, and then start again. Are there any other things I should try before resorting to that?
