Evening all I've been testing/evaluating lustre 1.6b5 and been having some stability problems. The setup is 1 mds, 4 oss's and 3 clients. oss's have 2 ost's each on raid5 (md) over 6 sata attached disks. All bar 1 client have dual gb nics (forcedeth). I've seen excellent bandwidth (~340GB/s aggregate) however there are some stability issues.
First, network interfaces occassionally drop out while running 6 instances of bonnie++ (3 per client). The mds has also crashed with a kernel panic after loosing its network. Second, I don't understand this error message: Dec 14 17:14:09 oss001 kernel: LustreError: 4777:0:(filter_io.c:537:filter_preprw_write()) dugeo-OST0000: trying to BRW to non-existent file 619123 This was around 30mins after an interface dropped out on a client (and reconnected some minutes later). Any ideas?
