To cleanup a brick previously used under glusterfs

Posted on by admin

This must be done after you REALLY know this brick is going to be re-used elsewhere not in the same volume it was used before.
NOTE: Potential data loss 

setfattr -x trusted.glusterfs.volume-id $brick_path
setfattr -x trusted.gfid $brick_path
rm -rf $brick_path/.glusterfs

mkdir ~/gluster
cd ~/gluster

wget -l 1 -nd -nc -r -A.rpm http://download.gluster.org/pub/gluster/glusterfs/LATEST/RHEL/epel-6/x86_64/

 

yum install glusterfs-libs-*.el6.x86_64.rpm -y

gluster peer probe <hostname of the other server in the cluster, or IP address if you don’t have DNS or /etc/hosts entries>


dd if=/dev/zero of=~/test.bin count=10000k
losetup /dev/loop0 test.bin

fdisk /dev/loop0 ---> new partition all blocks fdisk --> n -> p -> 1 -> from 1 to 637 in this case

yum install xfsprogs xfsdump -y

mkfs.xfs -i size=512 /dev/loop0 -f

--- Testing fs --------
mkdir /mnt/test
mount /dev/loop0 /mnt/test



--------fstab -----
