Dear List,
I'm using pvfs2 successfully on a cluster since now about 2-3 month,
with only one or two minor problems.
However, I have two questions to ask:
1) I have 4 masters that provides disk (all are meta data servers), say :
m001,m002,m003,m004
and n slaves that must access the servers.
pvfs2 is mounted using the kernel module.
Actually, for each slave, I use the following command :
mount -t pvfs2 ib://m001:3335/pvfs2-fs /SCRATCH
Is it a problem that all slaves goes through m001 ? Maybe it should
be better that 1/4 of the slave uses m001, 1/4 m002 , etc
in order to avoid a bottleneck, no ? I have no idea how this works.
2) Those last days, the pvfs2 disk space seems very low. Can it be
simply due to
the fact that all disks are nearly full (actually 95% )?
Filesystem Size Used Avail Use% Mounted on
3.4T 3.3T 189G 95% /SCRATCH
With best regards,
yves
