Problems with /etc/init.d/checkfs - software raid

[c_kuzmanic]

Hi,

I just successfully upgraded to Gentoo 1.4_rc1. Thanks to the update scripts, everything went smooth:)

There's just one problem with /etc/init.d/checkfs, when it is run at boot-time to start my software raid arrays (RAID0) the above mentioned script returns the following error:

sbin/runscript.sh : error: binary operator expected : Failed to start software RAID

Heres a listing of the relevant section from /etc/init.d/checkfs :


# Start software raid
if [ -x /sbin/raidstart -a -f /etc/raidtab -a -f /proc/mdstat ]
then
ebegin "Starting software RAID"
ACTIVE_RAID="`grep -E "md[0-9]+[[:space:]]?: active raid" /proc/mdstat | awk -F ':' '{print "/dev/"$1}'`"
if [ -n ${ACTIVE_RAID} ]
then
for x in $(grep -E "raiddev /dev/md[0-9]+" /etc/raidtab | \
awk '{print $2}' | grep -v "`echo ${ACTIVE_RAID} | sed s'/[[:space:]]//g'`")
do
/sbin/raidstart ${x}
done
else
/sbin/raidstart --all
fi
eend $? "Failed to start software RAID"
fi

Even though checkfs returns the above mentioned error, my software raid array is still initialised properly, due to (?)


---else
/sbin/raidstart --all
---fi

However, somewhere in the script there's an error which will pass a wrong value to grep/awk and give the error message.

My skills with awk are nill, therefore it would be nice if somebody could have a look at this and point me to a solution.

Just in case, here's my /etc/raidtab :
raiddev /dev/md1
raid-level 0
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hda3
raid-disk 0
device /dev/hdc3
raid-disk 1

raiddev /dev/md2
raid-level 0
nr-raid-disks 2
chunk-size 32
persistent-superblock 1
device /dev/hda4
raid-disk 0
device /dev/hdc4
raid-disk 1

and the output from cat /proc/mdstat :

Personalities : [raid0]
read_ahead 1024 sectors
md1 : active raid0 ide/host0/bus1/target0/lun0/part3[1] ide/host0/bus0/target0/lun0/part3[0]
81925632 blocks 32k chunks

md2 : active raid0 ide/host0/bus1/target0/lun0/part4[1] ide/host0/bus0/target0/lun0/part4[0]
72814016 blocks 32k chunks

unused devices: <none>

Any insights would be very much appreciated, probs with raid always make me nervous...

Ok, problem solved

I went over to bugs.gentoo.org to make a bug report and was delighted to see that the solution was already posted there:

Hope this helps any other people who might encounter this problem.
