How to expand the storage on fallopius
- You are the admin, right?
- Login as root and shutdown the machine
- Install the physical drives (currently, use only 1TB drives!). Turn on the machine.
- Enter the RAID bios by pressing TAB
- Enter the rsf menu and choose to expand the array (this operation took around 33 hours for 4Tb -> 6Tb expansion!!!)
- Enter the vsf menu and choose to expand also the logical array (this operation took only around 1 hour for 4Tb -> 6Tb expansion)
- Boot the system
- umount /home/; umount /storage/volume0; umount /storage/volume1
- Execute parted
- Select /dev/sdb. From now on we assume that in the system there exist, so far, logical partitions /dev/sdb1, /dev/sdb2, ..., /dev/sdb(n-1)
- Create a new partition, start at [old_size] (size before the RAID expansion), end at [new_size]. At the end of the process, the new partition is denoted as /dev/sdbn
- pvcreate /dev/sdbn
- vgextend users /dev/sdbn
- lvextend /dev/mapper/users-bigvol /dev/sdbn
- mount /storage/volume1
- xfs_growfs /storage/volume1
- mount /storage/volume0; mount /home/;
- DONE!!!!
