Hello List,
The lvm test default timeout (--timeout) default value is 180.
But I met below condition when running testcase (in virtual machine):
```
make check_local T=shell/snapshot-merge.sh
... ...
### passed: [ndev-vanilla] shell/snapshot-merge.sh 665
... ...
```
Hi
So your test seems to be very slow in 'mkfs.ext4':
[ 0:03] Creating journal (4096 blocks): done
[ 1:30] Writing superblocks and filesystem accounting information: done
....
[ 1:34] Creating journal (4096 blocks): done
[ 3:03] Writing superblocks and filesystem accounting information: done
....
[ 3:07] Creating journal (4096 blocks): done
[ 4:37] Writing superblocks and filesystem accounting information: done
....
[ 4:40] Creating journal (4096 blocks): done
[ 6:08] Writing superblocks and filesystem accounting information: done
....
This looks certainly seriously like a very slow (possibly doing TRIM) ??
Any idea why ?
The test seems to be using loop device created in backend file in your /tmp
(i.e.: losetup /dev/loop0 /tmp/LVMTEST11574.cJtNfnlPrj/test.img)
So any idea why your virtual machine is that slow with handling this case ?
One idea - aren't you using a storage with very slow discard processing
(i.e. ATM VDO) ?
You can setup different backend device or different location of test dir
(see 'make help' in test subdir)
