| |
Hi all,
I'm gathering together 15 sparse 1GB files distributed in 5 PCs with 3 files each to get a 15GB block device. I'm using nbd 1.4 and raidtools 0.42 in linear mode. Kernel is 2.2.15
I intend to use the block device as a debian archive mirror but after some amount of successful downloading the file system gets badly corrupted and I've to fse2ck it. I don't know whose fault it is raid?, nbd? Are they stable enough for this kind of work? Is anybody doing similar things? Can anybody help?
My setup is the following:
To start:
losetup /dev/loop0 .debian0 losetup /dev/loop1 .debian1 losetup /dev/loop2 .debian2 ./nbd-client soft8 60200 /dev/nd0 ./nbd-client soft7 60200 /dev/nd1 ./nbd-client soft6 60200 /dev/nd2 ./nbd-client soft5 60200 /dev/nd3
/sbin/mdadd /dev/md0 /dev/loop0 /dev/loop1 /dev/loop2 /dev/nd0 \ /dev/nd1 /dev/nd2 /dev/nd3 /sbin/mdrun -pl /dev/md0
nbd-server is started from inetd with a line:
nbd stream tcp nowait nbd /francesc0/local/bin/nbd-server nbd-server 0\ /francesc0/local/bin/.debian%%d 3072M -m
To stop:
/sbin/mdstop /dev/md0
# kill nbd-servers in soft5, soft6, soft7, soft8
losetup -d /dev/loop2 losetup -d /dev/loop1 losetup -d /dev/loop0
Cheers
