I have an even better idea (quick hack):
0. Turn off auto-sync: "gmirror configure -n <device name>"
1. we could schedule a gmirror-chk.sh execution every 5 minutes:
*/5 * * * * /root/gmirror-chk.sh
(note: crond is started after fsck)
2. /root/gmirror-chk.sh would look like this:
#!/bin/sh
gmirror status | grep / | cut -d/ -f2 | cut -d\ -f1 | \
while read dn ;do
na=""
fs=1
gmirror list $dn | \
while read ln ;do
if [ `echo $ln | grep -c "^[1-9]"` -ne 0 ]; then
if [ $fs -eq 1 ]; then
fs=0
else
na=`echo $ln | cut -d\ -f3`
fi
elif [ ! -z "$na" ]; then
if [ `echo $ln | grep -c "Flags: SYNCHRONIZING"` -ne 0 ]; then
gmirror rebuild $dn $na
break
fi
fi
done
done
[TESTED OK R6.1]
