Hi, I installed AS2.1 kernel 2.4.9-e.16 and Emulex driver v4.21g to connect Fujitsu raid through FC(fiber channel) cable. I met the lock problem by the follwoing operations: fdisk /dev/sdbX e2mkfs -j /dev/sdbX mount /dev/sdb1 /mnt/raid/X // run 16 sample programs for each mount point // pulled the FC cable and then some jobs abended. // 1 or 2 jobs were still running. // 'ps ax' showed the status D (disabled sleep) kill procid // not killed ls /mnt/raid/X => no response returned sync => no response returned I had to reboot to recover this situation. It seems someting lock was held. Could you give me any advice? Best regards Fujio Ikegami, Fujitsu _______________________________________________ Ext3-users@redhat.com https://www.redhat.com/mailman/listinfo/ext3-users
