[Lustre-discuss] Set quota on Lustre system file client, reboots MDS/MGS node
Hi I used lustre-1.8.3 for Centos5.4. I patched the kernel according to Lustre 1.8 operations manual.pdf. I have a problem when I want to implement quota. My cluster configuration is: 1. one MGS/MDS host (with two devices: sda and sdb,respectively) with the following commands: 1) mkfs.lustre --mgs /dev/sda 2) mount -t lustre /dev/sda /mnt/mgt 3) mkfs.lustre --fsname=lustre --mdt --mgsnode=<mgs IP at net> --param mdt.quota_type=ug /dev/sdb 4) mount -t lustre /dev/sdb /mnt/mdt 2. one OSS host (with two devices: sda and sdb as OST targets) with the following commands: 1) mkfs.lustre --fsname=lustre --ost --mgsnode=<mgs IP at net> --param ost.quota_type=ug /dev/sda 2) mkfs.lustre --fsname=lustre --ost --mgsnode=<mgs IP at net> --param ost.quota_type=ug /dev/sdb 3) mount -t lustre /dev/sda /mnt/ost1 4) mount -t lustre /dev/sdb /mnt/ost2 3. and one client with the following command: mount -t lustre <mds IP at net>:/lustre <IP at net%3E:/lustre> /mnt/client1 I tried to set quota for user1 with the following command: lfs quotacheck -ug /mnt/client1 lfs setquota -u user1 10240 10440 3 5 /mnt/client1 But the following problems occurred: when I ran the command, the MGS/MDS host is rebooted, so the process failed: Connection timed out I can not understand that a client "can" force it''s server to being rebooted and also, why the client forces the MGS/MDS host to reboot Any Idea?
