hello fellow CentOS Users,
on Scientific Linux 7 (_very_ similar to CentOS7), I get this when trying to mount NFS Shares (exported from Synology NAS) automatically at boot time:
[root@HOST ~]# journalctl -b 0 | grep NAS[20] Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS0... Jul 01 13:32:09 HOST systemd[1]: Mounting /mnt/NAS2... Jul 01 13:32:09 HOST systemd[1]: mnt-NAS0.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS0. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS0.mount entered failed state. Jul 01 13:32:09 HOST systemd[1]: mnt-NAS2.mount mount process exited, code=exited status=32 Jul 01 13:32:09 HOST systemd[1]: Failed to mount /mnt/NAS2. Jul 01 13:32:09 HOST systemd[1]: Unit mnt-NAS2.mount entered failed state.
I read that enabling NetworkManager-wait-online.service can mitigate that, but it's already enabled:
[root@HOST ~]# systemctl list-unit-files|grep wait chrony-wait.service disabled NetworkManager-wait-online.service enabled plymouth-quit-wait.service disabled
/mnt/NAS2 is defined in /etc/fstab (/mnt/NAS0 is mounted analogously):
NAS2HOST:/volume1/export/ /mnt/NAS2 nfs rw,vers=3,soft,bg,intr 0 0
This does not always occur, and it seems to be a race condition, because it did not occur a few months ago, before we moved offices (when only the networking changed slightly).
Of course, once the computer is booted, I can always mount the shares without problems.
Does someone have an idea?
Many Thanks and Best Regards,
