Best way to delay start of beegfs-storage

[Ray Muno]

I have BeeGFS storage nodes. The storage target is an iscsi mount.

What is the best way to configure beegfs-storage to start after the file system is mounted?

CentOS 7.9, BeegFS 7.2.5

The error I see is

Error: Found uninitialized storage target directory and initialization has been disable...storage

so I assume that is the issue. I can start it by hand after a boot.

What about modifying the systemd service file, adding the required targets to "After=",
and possibly setting "RequiresMountsFor="?

I took that approach.

I edited

/usr/lib/systemd/system/beegfs-storage.service

and added

remote-fs.target

to the After line.

I also had to add _netdev to the fstab line, to ensure the iscsi mount
succeeds at boot (not a BeeGFS issue per se).

It was starting just before multipathd started. I tried adding
multipathd.service to the After line, which pushed it down the chain a
bit, but it started while the filesystem was mounting, but before the
XFS filesystem fully came on line.

This is working through multiple reboots, but it seems odd to me since I
would not view an iscsi hosted filesystem as one that is remote.

Perhaps there is a better target to use as a requirement.
