[Gluster-users] broken after IPs changed

[Костырев Александр Алексеевич]

Yep, that’s exactly what happened

 

Guys from IRC #gluster helped me to solve the problem – thanks to them.

 

To solve:

1.       getfattr -m .  -d -e hex /mnt/ld0  <-- get the xattrs

2.       setfattr -x “list of xattr (step1) “ /mnt/ld0

 

for all bricks

and then gluster volume create … again

You probably want to blow away your brick filesystem and start clean - There will be xattr information that is confusing Gluster.

Best practice is to use DNS to support peers, rather than IP addresses.

Hello!




I fired up gluster v.3.2.5 with this:

 

gluster peer probe 10.0.1.131

gluster volume create vms replica 2 transport tcp 10.0.1.130:/mnt/ld0 10.0.1.131:/mnt/ld3 10.0.1.130:/mnt/ld1 10.0.1.131:/mnt/ld4 10.0.1.130:/mnt/ld2 10.0.1.131:/mnt/ld5

gluster volume start vms

mkdir /mnt/gluster

 

added in /etc/fstab

127.0.0.1:/vms /mnt/gluster glusterfs defaults,_netdev 0 0

mount /mnt/gluster

 

everything was awesome

 

than for some reason I had to change IPs of my servers

from

10.0.1.130 -> 10.0.1.50

10.0.1.131 -> 10.0.1.51

 

I’ve decided to 

stop my volume,

delete it,

stop glusterd,

erase gluster software (and all configs) with yum (Centos 6.2 x86_64)

and then recreate that volume again with:

gluster peer probe 10.0.1.51

gluster volume create vms replica 2 transport tcp 10.0.1.50:/mnt/ld0 10.0.1.51:/mnt/ld3 10.0.1.50:/mnt/ld1 10.0.1.51:/mnt/ld4 10.0.1.50:/mnt/ld2 10.0.1.51:/mnt/ld5

 

but  it said:

Operation failed

 

I googled for awhile and found out that new 3.3.0 has arrived, so I updated to it and start whole thing over again

Now It says:

/mnt/ld0 or a prefix of it is already part of a volume

 

Any help ?

Thanks in advance
