[Nbd] NBD with RAID1
Hi,
I set up NBD with RAID1 for replicating a file server.
The system is Debian Sarge (kernel 2.6.8) with a dedicated Gigabit link
for NBD (1.1 TB x 2). The filesystem is XFS.
I had some problem with NBD 2.7.3, but these seems resolved with NBD
2.7.4 from Debian Testing.
kernel: nbd0: Receive control failed (result -32)
kernel: nbd0: queue cleared
kernel: nbd0: NBD_DISCONNECT
kernel: md: trying to remove unknown-block(43,0) from md0 ...
kernel: md: cannot remove active disk nbd0 from md0 ...
After some testing, I decided to cut the data space in several
partitions, which allows several NBD processus to work in parallel.
I had to rewrite the startup script for nbd-client, and made another
script for monitoring the link between the servers. I am thinking to use
heartbeat for that. Did anyone have the same issue ? Which solution was
adopted ?
Best regards,
Yann
