There are 2 file in the xfs device, md5 is the same, but the size is different.
I don't know why .......
Does anyone could help me?
Server1 is EMC Isilon export from NFS (mount point: A, onefs)
Server2 is rack server export from NFS (mount point: B, xfs)
Login node could access A and B by NFS client, and then "copy /A/xxx/xxx to /B/xxx/xxx", the file size is different.
I Switch to Server3 , and use jfs or ext3, it 's ok.
mount point:
df -h /export/data1/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb 17T 13T 4.1T 76% /export/data1
I don't know why their "Blocks" is different.
