Re: [Moosefs-users] something about mfs.cgi

Hi!

 

This is information about deleting individual chunk copies not the whole
chunks. Such operations (apart from deleting files from the system) happen
also when you decrease goal for the given file or while rebalancing
replications. If there are any chunks on an Info tab marked in blue - this
means they have more copies than planned and are to be deleted. While
rebalancing - first a copy on a server with more free space is created and
later (after several minutes) a copy from the more occupied server is
deleted.

 

 

Kind regards

Michał

Hi, all.

The "Master Charts" at the cgi script, It shows that "chunk deletions (per
minute) " is very high, for about 70, and it continued for about 3 hours. 

But at the trash directory which mount by " /opt/app/mfs/bin/mfsmount -m
/mnt -H 192.150.26.100", It shows only for about only 10 files during the
past 3 hours. Also we checked the log of our application, it shows no file
deletions at those time. 

So I wonder why "chunk deletions (per minute) "  at the  mfs.cgi script
report so high.

Anybody else has met the same situation? And what happend with MFS?

Thanks all.
