Describe the issue: Brick configurations steps in the RHGS 3.0 admin guide are somewhat complicated because, at the time, LVM only supported Volume Group extent sizes that were a power of 2. Suggestions for improvement: bz 1100514 requesting support for non-power-of-2 physical extents has been fixed and is available in both RHEL 6.7 and RHEL 7.1. Since RHGS 3.1 will be on RHEL 6.7 and RHEL 7.1, we should now simplify the brick configuration steps. Additional information:
Steps to be followed for Brick Configuration: 1. create pv [no change] 2. create vg a. RAID-6 and RAID-10: vgcreate --physicalextentsize <pe_sz> <vg_name> <pv_name> where pe_sz = (stripe_unit size) * (number of data disks) b. JBOD: vgcreate <vg_name> <pv_name> 3. create thin pool command: lvcreate --thinpool <pool_name> --size <pool_size> --chunksize <chunk_size> --poolmetadatasize <meta_size> <vg_name> - thin pool chunk size recommendation: [no change RAID-6: (stripe_unit size) * (number of data disks) RAID-10: 256K JBOD: 256K] - pool metadata device size recommendation [no change] - turn off block zeroing in thin pool [no change] 4+. thin lv and file system creation [no change]
made the required changes based on my discussion with Manoj. http://jenkinscat.gsslab.pnq.redhat.com:8080/job/doc-Red_Hat_Gluster_Storage-3.1-Administration_Guide%20%28html-single%29/lastStableBuild/artifact/tmp/en-US/html-single/index.html#Brick_Configuration
validated and was able to create LVs using doc 11.2. Brick Configuration followed all steps and was successful hence marking as verified [root@rhgs-6 ~]# cat /etc/redhat-* Red Hat Enterprise Linux Server release 6.7 (Santiago) Red Hat Gluster Storage Server 3.1
