-y answer 'y' to usage question (only when --rsync used)
-0 input file names on stdin are separated by a null character
-Options '-A', '-c', and '-R' are mutually exclusive.
+Options '-A', and '-R' are mutually exclusive with each other, and any
+specific layout (e.g. any specific parameters like '-c', '-S', '-E', '-p').
Options '-C', '-M', and '-X' are ignored if '-A' is not set.
If a directory is an argument, all files in the directory are migrated.
If emptying an active OST, new files may continue to be allocated there.
To prevent this, on each MDS run the following for each OST being emptied:
- lctl set_param osp.<fsname>-OSTNNNN*.max_create_count=0'
+ lctl set_param osp.<fsname>-OSTxxxx*.max_create_count=0
Examples:
lfs_migrate /mnt/lustre/dir
