Description Pino Toscano 2019-11-07 14:53:23 UTC 
Created attachment 1633684 [details]
Fixed service files

Description of problem:
mdadm 4.1-9 adds few new service files:
- /lib/systemd/system/mdcheck_continue.service
- /lib/systemd/system/mdcheck_start.service
- /lib/systemd/system/mdmonitor-oneshot.service
I noticed that augeas [1] cannot parse these files, with parse errors in the Environment= keys.
In particular, there are double quoting, and even more covering just the values and not the whole Environment= string (at least, according to my reading systemd.service(5) man page).
Furthermore, the two mdcheck_*.service files refer to /usr/share/mdadm/mdcheck in ExecStart=, and that executable does not even exist.

[1] a library to parse & edit configuration files

Version-Release number of selected component (if applicable):
mdadm 4.1-9

How reproducible:


Steps to Reproduce:
1. install mdadm and augeas
2. run `augtool print /augeas//error | grep lib/systemd/system`

Actual results:
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error = "parse_failed"
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error/pos = "341"
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error/line = "12"
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error/char = "0"
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error/lens = "/usr/share/augeas/lenses/dist/inifile.aug:497.25-.43:"
/augeas/files/lib/systemd/system/mdmonitor-oneshot.service/error/message = "Get did not match entire input"
/augeas/files/lib/systemd/system/mdcheck_start.service/error = "parse_failed"
/augeas/files/lib/systemd/system/mdcheck_start.service/error/pos = "370"
/augeas/files/lib/systemd/system/mdcheck_start.service/error/line = "14"
/augeas/files/lib/systemd/system/mdcheck_start.service/error/char = "0"
/augeas/files/lib/systemd/system/mdcheck_start.service/error/lens = "/usr/share/augeas/lenses/dist/inifile.aug:497.25-.43:"
/augeas/files/lib/systemd/system/mdcheck_start.service/error/message = "Get did not match entire input"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error = "parse_failed"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error/pos = "409"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error/line = "14"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error/char = "0"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error/lens = "/usr/share/augeas/lenses/dist/inifile.aug:497.25-.43:"
/augeas/files/lib/systemd/system/mdcheck_continue.service/error/message = "Get did not match entire input"

Expected results:
No output

Additional info:
I tried to fix the .service files according to the documentation, although I did not have the possibility to test them; I will attach them.

Hi All,

I've talked with xni, and did the test on mdadm-4.1-11.el8.
on mdadm-4.1-11.el8 the mdcheck_start.service could start normally,but still got some output from "augtool print /augeas//error | grep lib/systemd/system".

xni has made mdadm-4.1-13.el8, which I've tested too, it works well with both "mdcheck_start.service" and "augtool" problem, but we still need to wait for the upstream's accept.
so I changed the status into VERIFIED.
