Subject: Locking md device and system for several seconds
Date: Sun, 13 Nov 2005 11:31:50 +0100 [thread overview]
Message-ID: <014101c5e83d$759c3df0$4001a8c0@MDSYSPORT> (raw)
Hi!
I'm using kernel 2.6.14.2 with md (RAID1 static) as bootable.
While md synching (initial creation or after marked one as failed,
removed and re-added) there are some locking problems with the
complete system/kernel.
Sometimes the system hangs (looks like a file/disk-access-lock)
while other tty's still work (until they access also to the disk).
This "hang" is some seconds (most from 10s up to 1 minute, seldom
more) and surprisedly the system continues working.
If md is in correct state (all partitions synced) this issue
doesn't seem to appear.
Configuration
4 Partitions (/boot 1GB, / 32GB, swap 16GB, /home 250GB) on
MaxLine III SATA 300GB Disks. Each of them (including swap)
is a RAID 1 device in the listed order.
This system has a Opteron 270 with nVidia Professional Chipset.
There are NO log entries found anywhere and no console warning/error.
These are 4 systems with she same behaviour.
Did anybody ever reported such an issue or has an idea?
