Hi everyone, on starting an OST I get this message in the log:
Lustre: zn_atlas-OST0000: underlying device cciss/c1d0p1 should be tuned for larger I/O requests: max_sectors = 1024 could be up to max_hw_sectors=2048 /dev/cciss/c1d0p1 is a RAID6 on a HP Smart Array P800 controller with 12 750 GB SATA drives. The stripe size is 128 KB according to the hpacucli script. The OST was created with mkfs.lustre --fsname=zn_atlas --ost --mkfsoptions="-E stride=32 -E stripe-width=320 -J device=/dev/vg00/j-ost0 -i 1048576" --mgsnode=192.168.22...@o2ib1,141.34.21...@tcp0 /dev/cciss/c1d0p1 What can I do?
