Package: e2fsprogs Version: 1.45.2-1 Severity: normal File: /sbin/e2scrub Hi,
once in a while, I get mail from one of my systems saying that e2scrub for /, /boot and a bunch of other filesystems has failed. The log says, for example: Jul 3 19:18:51 fan systemd[1]: Starting Online ext4 Metadata Check for /... Jul 3 19:18:51 fan e2scrub@-[24727]: /: Not connnected to an LVM logical volume.

Jul 3 19:18:51 fan e2scrub@-[24727]: -V: Print version information and exit. Jul 3 19:18:53 fan systemd[1]: e2scrub@-.service: Main process exited, code=exited, status=1/FAILURE Jul 3 19:18:53 fan systemd[1]: e2scrub@-.service: Failed with result 'exit-code'. Jul 3 19:18:53 fan systemd[1]: Failed to start Online ext4 Metadata Check for /. Jul 3 19:18:53 fan systemd[1]: e2scrub@-.service: Triggering OnFailure= dependencies.

Jul 3 19:18:54 fan systemd[1]: e2scrub_fail@-.service: Succeeded. The problem is that the error message is fully correct: / is not an LVM logical volume, it's a LUKS device stored on an LVM logical volume: 32 [5/4992]mh@fan:~ $ lsblk /dev/sdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdb 8:16 0 931,5G 0 disk ├─sdb1 8:17 0 1007K 0 part ├─sdb2 8:18 0 1M 0 part └─sdb3 8:19 0 931,5G 0 part ├─fan-c_root 253:0 0 417,2G 0 lvm │ └─root 253:28 0 417,2G 0 crypt / To make things more complex, the whole thing seems to be invoked by e2scrub_all.timer, which in turn calls e2scrub_all.service, which in turn calls /sbin/e2scrub_all -C which runs just fine when invoked from the shell: |[8/4995]mh@fan:~ $ time sudo /sbin/e2scrub_all -C | |real 0m9,014s |user 0m0,121s |sys 0m0,069s |[9/4996]mh@fan:~ $ ... but ... (additional issue #1) the -C option is not mentioned in the e2scrub_all manual page, ... and ... (additional issue #2) e2scub_all -n reveals that it would actually invoke systemctl start e2scrub@- which, manually invoked, gives some feedback about its failure: [11/4998]mh@fan:~ $ sudo systemctl start e2scrub@- Job for e2scrub@-.service failed because the control process exited with error code. See "systemctl status e2scrub@-.service" and "journalctl -xe" for details. (exit code 1) I think that this should be reported by e2scrub_all so that the user isn't lured into "everything is fine". I don't think that having an e2 file system on a LUKS device on an LVM logical volume is such an exotic thing to have. Please let me know if you want dedicated bug reports for the additional issues #1 (minor) and additional issues #2 (normal).
