During some many ost tests i ran this month i ran into a problem where i cannnot mount formatted OSTs very quickly. Here is my setup: All nodes are dual IA64 1.5Ghz nodes. 570 OST's with a RAID0 OST each. I format and mount the mgs/mdt as such on m978: mkfs.lustre --reformat --mgs --comment "TestMGS" /dev/sda7 mkfs.lustre --reformat --mdt --fsname=mpp2_r0 --comment "Really Big OST Test MDT raid0" [EMAIL PROTECTED] /dev/sdb7 mkdir /l mkdir /l/mgs mkdir /l/mdt mount -t lustre /dev/sda7 /l/mgs mount -t lustre /dev/sdb7 /l/mdt I format the ost's as such: $MKFS --ost --index=$num --fsname=$fsname [EMAIL PROTECTED] --comment "$(hostname) md9" --reformat /dev/md9 where $num is based on the node number(0-569) then I attempt to mount the ost's with a pdsh: pdsh -w m[0-569] mount -t lustre /dev/md9 /l/md9 almost immediatly the MGS and OST nodes start complaining. This happens in the first 32 nodes(pdsh default fan-out) ( i'll attach console logs to the bug momentarilly) If i reduce the pdsh fanout to 8 things work fine, but it takes 10-20 minutes to mount lustre ost's I saw this problem before in 1.5.95 wit 7 OST's per OSS, and had to reduce fanout to 2. _______________________________________________ Lustre-devel mailing list Lustre-devel@clusterfs.com https://mail.clusterfs.com/mailman/listinfo/lustre-devel
