I've only run GFS2 on RHEL5. It's been quite reliable, but
Hi all,
If you have had experience hosting GFS/GFS2 on CentOS machines could
you share you general impression on it? Was it realiable? Fast? Any
issues or concerns?
Also, how feasible is it to start it on just one machine and then grow
it out if necessary?
Thanks.
Boris.

Two web servers, both virtualized with CentOS Xen servers as host
(residing on two different physical servers).
GFS used to store home directories containing web document roots.
Shared block device used by GFS is an ISCSI target with the ISCSI

Not only sorting, but usually "ls" ends up trying to find out if the

Hi,
independently from the results you have seen it might be always reasonable to
tune a gfs filesystem as follows:

specially
mount with noatime and

Hi all,
We are running CentOS 5.2 64bit as our file server.
Currently, we used GFS (with CLVM underneath it) as our filesystem
(for our multiple 2TB SAN volume exports) since we plan to add more
file servers (serving the same contents) later on.
The issue we are facing at the moment is we found o

So, how do you have your setup?
How many nodes? I need something stable so I will look into GFSv1, but may
consider GFSv2 later on.

GFS works well, gfs2 is at the moment in technology-preview mode only,
but its still worth looking at.

I have a (CentOS4.5) cluster in which the servers mount a GFS partition
which is an LVM2 logical volume created as a mirror of two iSCSI-
connected drives (with a third for the log). The LV was created using a
command along the lines of:
