Hi
I have two Linux boxes running kernel 2.4.21 having access to two
devices over fibre channel SAN.
What I'm trying to achive is host based mirroring with ability to
move the storage from one host to another.
On the firs host I created a raid1 array, put LVM on it, created a
filesystem. To move
Hi
I've just noticed that setting an array readonly doesn't really make
it readonly.
I have a RAID1 array and LVM on top of it.
When I run
/sbin/mdadm --misc --readonly /dev/md0
/proc/mdstat shows:
Personalities : [raid1]
md0 : active (read-only) raid1 sda[0] sdb[1]
160436096 blocks
Hi
Is there any way to lock an active array?
To make clear what I'm after:
I have two machines forming a fail-over cluster connected over SAN to
two storage boxes which provide them with a disk each.
I created a RAID1 using those two disks.
Both cluster nodes see both disks but only one

Any comments, ideas?
Would that not imply an unlock
I was thinking about it, I have no idea how to do it on Linux if ever possible.
I connect over fibre channel SAN, using QLogic QLA2312 HBAS, if it matters.
Anyone any hints?
Thanks and regards,

It looks like we are the only two md users interested in such a
feature.
Not enough to get Neil's attention ;-)

I have currently four clusters which mirror shared storage. I've
always pay great attention not to have an array active on both
cluster nodes. I can imagine data corruption would happen soon or
late.
Unfortunately md lacks the ability to mark an array as
