[Gluster-users] adding third brick to replica volume and suddenly files need healing

[lejeczek]

hi guys

I've had two replicas volume, added third brick and now I see hundred
thousand files to heal, interestingly though only on two bricks that
already constituted the volume.
Volume prior to expansion was, according to gluster, okey and when I
added third brick it immediately started increasing count of files in
need of healing.

I that normal behavior? (and if not then how to troubleshoot it? $ heal
full does not seem to do anything, unless it takes time for over 100K
files on a fairly slow storage?)

I do heal info and I see a lot of:

Hi,

That's normal, the heal is how it syncs the files to the new bricks.
And yes, the heal shows on the sources, not on the destination, which is
a bit weird but that's just how it is :)
