Title:
Bionic (4.15.0-62.69): lvremove of 2TB LV reports: 'BLKDISCARD ioctl
operation not supported'
Status in linux package in Ubuntu:
Expired
Bug description:
While tracking down a lockup while running `lvremove` on a 2TB sized LV with
4.15.0-58.64, I noticed that upgrading to 4.15.0-62.69 makes the operation
succeed, but still print:
```
/dev/mapper/test: BLKDISCARD ioctl at offset 1048576 size 6442450944000
failed: Operation not supported.
```
Looking into the commits before 4.15.0-58.64 it seems that the issue
got introduced with 3c2f83d8bcbedeb89efcaf55ae64a99dce9d7e34 in
ubuntu-bionic.
AFAIS the commit did not make it into 4.14 or 4.19 stable, but got pulled
from 4.18.
see https://www.mail-archive.com/[email protected]/msg1897789.html
for a short discussion why it did not got pulled into the LTS series upstream.
While a55264933f12c2fdc28a66841c4724021e8c1caf fixes the infinite loop
on `lvremove` it seems that a backport of
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4800bf7bc8c725e955fcbc6191cc872f43f506d3
would correctly address the issue.
Glad to provide further information and help testing!
Thanks!
