[Ocfs2-users] No Space left on the device.

[Aravind Divakaran]

Hi,

I am facing problem due to free space fragmentation.

http://oss.oracle.com/bugzilla/show_bug.cgi?id=1189.

In the above link it is mentioned that reducing the slots can solve the
issue. Right now i have 4slots. As my ocfs device is configured for a
failover for mailserver of 2systems, if i reduce it to 2slots whether i
can solve this issue. Please let me know if this is the command i have to
give to reduce the slots to 2.

tunefs.ocfs2 -N 2 /dev/mapper/store

Rgds,
Aravind M D
