Hi,
my configuration is a default RH8.0:
[root@frogproject root]# rpm -qa |grep raid
raidtools-1.00.2-3.3
[root@frogproject root]# uname -a
Linux frogproject.soft.sdesigns.com 2.4.18-14 #1 Wed Sep 4 13:35:50 EDT 2002 i686 i686 i386 GNU/Linux
[root@frogproject root]#
I have setup a RAID5 software on five identical IDE drives hdb, hdc, hde, hdf, hdg
Starting with:
0:hdf 1:hdc 2:hde 3:hdg spare:hdb
without recovery thread running, I just wanted to remove hde from the array to see the
recovery thread using the spare hdb. Unfortunately this causes:
# raidhotremove /dev/md0 /dev/hde1
/dev/md0: can not hot-remove disk: disk busy!
Even if user operation is bad, I should not get this log:
