I'm using this setting for XFS: 1. mkfs.xfs --l logdev=/dev/sda1,size=64m --d agcount=32 /dev/test/department 1. mount -o noatime,nodiratime,nobarrier,logbufs=8 /dev/test/department /data/ My current situation is : 1) I'm using XFS file system as my files server 2) i'm using snapshot to make a hot backup like shadow copies in windows The problem is it takes a long time and some time it make time out for: 1) New file creation 2) Copy files from xfs shared to another local pc's ** what have i check is; if no snapshot was taken; the files sharing was go on without problem and really fast. This problem occurred only when we have a snapshot drives. even a single drive. please help me and advise me on this? Regards Rozi [[HTML alternate version deleted]]
