If i start a backup job, smb stops working.
The priority of rsync is to high

Code Select

my quick and dirty solution is

Code Select

crontab -l >/tmp/rsync.crontab ;
echo '*/1 * * * * /usr/bin/renice -n 19 $(/bin/pidof rsync)' >>/tmp/rsync.crontab ;
crontab < /tmp/rsync.crontab ; rm /tmp/rsync.crontab

use renice

example:

Code Select

# renice -n 0 `pgrep "[s]mbd"`

i am using
renice -n 19 $(/bin/pidof rsync)

from
echo '*/1 * * * * /usr/bin/renice -n 19 $(/bin/pidof rsync)' >>/tmp/rsync.crontab

but i hope this bug will be fixed in the next firmware

where can i report a bug to buffalo?
