| − | from bug 5665
| |
| − | The newer e2fs tools are smart enough that if you use the resize2fs tool to do
| |
| − | the resizing with a mounted filesystem it will do the same thing ext2online
| |
| − | used to do. They just made it so instead of having two tools you have one
| |
| − | smart tool.
| |
| | | | |
| − | That being said the documentation may need to be updated to handle the sme8
| |
| − | case. However there are a lot of enhanced things you can do with the new tools
| |
| − | in 8 that you can't do in 7. I'd like to see an entire new page explaining how
| |
| − | to expand/grow your filesystem on 8 instead of just adding notes for where
| |
| − | things are different.

| − | ====Replacing and Upgrading Hard Drive after HD fail====
| |
| − | Note: these instructions are applicable if you have a faulty HD on a RAID system with more than one drive and intend to upgrade the sizes as well as replacing the failed HD. They are not applicable to a single-drive RAID 1 system, and increasing the useable space on such a system by cloning the existing single drive to a larger drive is not supported. See http://bugs.contribs.org/show_bug.cgi?id=5311

| − | HD Scenario - Current 250gb drives, new larger 500gb drives
| |
| − |
| |
| − | # Remove failed HDD from system, ensure remaining drive is on sda on its own and boot up.
| |
| − | # Shutdown, connect one new 500gb drive as sdb and boot up
| |
| − | # Login to the admin panel and manage raid to add new (larger) drive to system.
| |
| − | # Wait for raid to fully sync
| |
| − | # Do full reboot with those 2 drives in place (1 original, 1 new)
| |
| − | #Shutdown again, disconnect the original drive, and connect the new drive just sync'd as sda (in place of original)
| |
| − | # Boot up again with just the one new drive in place, and confirm it boots OK.
| |
| − | # Shutdown, and connected the other 500gb drive as sdb
| |
| − | # Boot up login to admin panel and add sdb to the array, and wait for raid to fully sync.
| |
| − | # Reboot and ensure all drives have been replaced with larger drives and array is in sync and redundant!
| |
| − | # Issue the following commands:
| |
| − |
| |
| − | mdadm --grow /dev/md2 --size=max
| |
| − | pvresize /dev/md2
| |
| − | lvresize -l +100%FREE main/root
| |
| − | ext2online -C0 /dev/main/root
| |
| − |
| |
| − | In the last command above, the -C0 is: dash C zero
| |
| − |
| |
| − | If you receive an "command not found" error, try this:
| |
| − | resize2fs /dev/mapper/main-root &
| |
| − |
| |
| − | TIP: I put an "&" at end to allow it to run in background even if I close ssh session.

| |
| − | Notes :
| |
| − | * These instructions should work for any raid level you have as long as you have >= 2 drives
| |
| − | * If you have disabled lvm
| |
| − | # you don't need the pvresize or lvresize command
| |
| − | # the final line becomes ext2online -C0 /dev/md2 (or whatever / is mounted to)
