See progress of lvm --merge

Question

Is there any way I can see the progress of a merge of my snapshot back to the origin?

The only thing I know is that there is an ongoing merge because I can't create a new snapshot.

When running lvconvert, use the interval flag. From the man page:

-i, --interval Seconds

Report progress as a percentage at regular intervals.

And if I didn't do that? No way to see it then? Or even abort it? As far as I can tell it's not doing any progress and I can't abort it. – Andreas Wederbrand Dec 10 '13 at 09:33
I don't know. You could ask on the linux-lvm mailing list. https://sourceware.org/lvm2/ – sciurus Dec 10 '13 at 14:20

`lvs -a`: Data% columns will go down to 0% while merging – sherpya Apr 08 '15 at 02:20

run

watch -n 1 "ps auxf | grep lvm | grep -v grep"

And check to see if the time column is going up. If it is you know the program is using CPU time.

Try `ps auxf | grep [l]vm` for an easy hack that removes the need for `grep -v`. – Alexios Mar 16 '14 at 15:32
