Hi,
I'm looking for a way to create a real-time mirror of a NAS. In other
words, say I have a 5.5 TB NAS (3ware 16-drive array, RAID-5, 500 GB
drives). I want to mirror it in real time to a completely separate 5.5
TB NAS. RSYNCing in the background is not an option. The two NAS boxes
need to

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
used/busy/you_name_it. Sometime
andy Here's a concrete example. I have two 3ware RAID-5 arrays, each
andy made up of 12 500 GB drives. When presented to Linux, these are
andy /dev/sda and /dev/sdb -- each 5.5 TB in size.
andy I want to stripe the two arrays together, so that 24 drives are
andy all operating as one unit.
Hello andy,
al Can I export NAS B as a SAN or ISCSI target, connect the two machines
Am I right in the assumption that your NASes are Linux boxes? :)
Did you take a look at Linux Network block devices (nbd/enbd)? They
might be what you need: you'd get a raw device on one of the servers
to use in

I appear to have a corrupt file system and now it is mirrored. LOL.
I am running Redhat Enterprise 3 and using mdtools.
I booted from the install media iso and went into rescue mode. RH was
unable to find the partitions automatically but after exiting into
bash i can run fdisk -l and i see all
