...loud. If the VMs are forcibly rebooted without enough time to complete a heal before the next one goes down, then it cannot be guaranteed that the data is safe?

Xavi, does that mean that even if every node was rebooted one at a time even without issuing a heal that the volume would have no issues after running gluster volume heal [volname] when all bricks are back online? ________________________________ From: Xavi Hernandez <jahernan at redhat.com> Sent: Thursday, March 15, 2018 12:09:05 AM To: Victor T Cc: gluster-users at gluster.org Subject: Re: [Gluster-users] Disperse volume recovery and healing Hi Victor, On Wed, Mar 14, 2018 at 12:30 AM, Victor T <hero_of_nothing_1 at hotmail.com<mailto:hero_of_nothing_1 at ho...

I'm considering different options to provide HA (pacemaker/corosync, keepalived or using VMs - RHEV - to deliver storage). Thank you for your reply.

Hi, You can set disperse.shd-max-threads to 2 or 4 in order to make heal faster. This makes my heal times 2-3x faster. Also you can play with disperse.self-heal-window-size to read more bytes at one time, but i did not test it.

The referenced GitHub issue now has a potential patch that could fix the problem, though it will need to be verified. Could you try to apply the patch and check if the problem persists ?

I have a question about how disperse volumes handle brick failure. I'm running version 3.10.10 on all systems. If I have a disperse volume in a 4+2 configuration with 6 servers each serving 1 brick, and maintenance needs to be performed on all systems, are there any general steps that need to be taken to ensure data is not lost or service interrupted? For example, can I just reboot each system

Hello I'm running some tests to compare performance between Gluster FUSE mount and formated sparse files (located on the same Gluster FUSE mount). The Gluster volume is EC (same for both tests). I'm seeing HUGE difference and trying to figure out why. Here is an example: GlusterFUSE mount: # cd /mnt/glusterfs # rm -f testfile1 ; dd if=/dev/zero of=testfile1 bs=1G count=1 1+0 records
