We started using gluster in a custom solution recently. Basically we
setup a gluster volume that we mount at /home. Then we give users their
own home directory with a gluster quota. They have FTP, SFTP and
SSHMOUNT access. I first used vsftpd and notice that ftp connections
will not close and the load goes up ever couple of days the funny thing
is the load does not seem to slow down the server. The load went up to
20 in the last two months but the server was not slow at all... At first
I thought it was vsftpd so I changed to proftpd then the issue came
back. If I reboot the server it goes away for a few days depending on
how many ftp connections. I noticed in the dmesg log this making me
think the issue was some kind of leak in gluster-fuse
This is on CentOS 6.5 64 bit.
