[Gluster-users] How do I increase volume space on a gluster disperse volume

[Leung, Alex (398C)]

Got a tons of error messages from the export-gfs.log, any ideas what is that and how to fix this.

The message "W [MSGID: 122053] [ec-common.c:116:ec_check_status] 0-pdsclust-disperse-0: Operation failed on some subvolumes (up=3F, mask=1F, remaining=0, good=1F, bad=20)" repeated 3 times between [2016-10-11 13:32:04.509834] and [2016-10-11 13:32:06.008820]

Thanks

    Yes the command is like that.

    You don't want to do that, 20TB from 40TB is wasted. Bricks should be same size.
