systemctl bug?

audiomuze · 2016-04-23 20:14:06

Following a frwesh install of Arch on a 16GB ext4 formatted flash drive I get this when stopping a service:

# systemctl stop roonserver
Failed to add /run/systemd/ask-password to directory watch: No space left on device

Any idea what's causing it?

A full /run?

df -h

If /run is full something is seriously broken as it is a tmpfs and usually (at least here) is always almost empty.

I've defined a few locations as tmpfs in /etc/fstab (booting from a USB flash drive and want to minimise unnecessary writes to it):

tmpfs      /var/log			tmpfs     defaults            	0    0                 
tmpfs      /var/tmp			tmpfs     defaults            	0    0
tmpfs      /tmp				tmpfs     defaults            	0    0
tmpfs      /mnt/ssd/RAATServer/Logs	tmpfs     defaults              0    0
tmpfs      /mnt/ssd/RoonServer/Logs	tmpfs     defaults              0    0
tmpfs      /mnt/ssd/RoonServer/Temp	tmpfs     defaults              0    0

Googling:

Failed to add /run/systemd/ask-password to directory watch: No space left on device

shows many hits mentioning systemctl bug?

If you really think its a systemctl bug go ahead and do a proper bug report. Otherwise, there is the following (using your google search query exactly): http://serverfault.com/questions/663824 … -available and similar ones on serverfalt. There is also this one http://askubuntu.com/questions/154255/h … fy-watches which relates to inotify watches; a likely solution imo. Please don't take offence to this, but it might help to actually try and do something with your google searches, instead of telling us that you searched it.

For debugging you can try without all the tmpfs mounts and see if the problem goes away, if it does then add one thing at a time until the problem comes back.

On the other hand, I wouldn't worry too much about the extra writes, specially if you are using something like btrfs or f2fs. I'd say you will run out of free space or get bored of slow speeds before the flash drive kicks the bucket.
