[Ocfs2-users] Question/Issue with copy of OCFS areas.

[Kilgore, Phil]

OCFS 2  namely ocfs2-1.2.7

 

Linux is Red Hat rel 4 2.6.9.22 SMP

 

I have a SR open  7045509.994 but was wondering if you knew about any
issues like below.

 

I have an existing database on OCFS which I want to move to new disk
areas.

The new areas I formatted with OCFS 4k block 256k cluster block. The old
area is probably 4K cluster blk 64K

I can copy database to this new area from old area no problem.

When I attempt to copy it back from new to old area I get the below....
Does it every time after about 10 minutes. I am doing a standard copy.

 

Any help or advice would be appreciated; I have been fighting this now
for over 3 weeks.
