| Description |
|
This issue was mentioned when Lustre performance was tested on ZFS. To reproduce this, set a CPU offline: [root@centos7 tests]# echo 0 > /sys/devices/system/cpu/cpu0/online [root@centos7 tests]# cat /sys/devices/system/cpu/cpu0/online 0 [root@centos7 tests]# REFORMAT=yes OSTCOUNT=4 sh llmount.sh Stopping clients: centos7 /mnt/lustre (opts:) Stopping clients: centos7 /mnt/lustre2 (opts:) Loading modules from /Users/jxiong/srcs/pfl/lustre/tests/.. detected 4 online CPUs by sysfs Force libcfs to create 2 CPU partitions ../libcfs/libcfs/libcfs options: 'cpu_npartitions=2' insmod: ERROR: could not insert module /Users/jxiong/srcs/pfl/lustre/tests/../../libcfs/libcfs/libcfs.ko: Operation not permitted Really easy to be reproduced. |
