Remounting partitions, out of disk space.

[Solokron]

I have run into an interesting issue on a server. I am aware there may be different fixes. I wonder what you have used to correct this successfully?

I have the / partition around 9GBs which is not sufficient for local backups or even temporary space for remote backups. /home partition was set to fill the rest of the hard disks space.

What I would like to do is remount the /home/ partition as / and move its contents to a new directory named /home/ on the new mount.

Anyone successfully perform this? What was used, RAM drive, simple remounting via fstab, transfer to new server, partition software?

Thank you.

What we have done is purchased a new drive and created a mount point /backup in it. After that we have configured backup in /backup directory.

I will not take risk of remounting /home since it holds my customers user directories.

The safest thing to do is just get another drive added. I don't suggest playing with the drive's partitions with live data on it.

Server already full with 2x 1TB drives in RAID 1. New drive is not an option.

Since you are running RAID1, why you dont just create a symlink on / partition pointing to a 2nd disk folder?

 

[Solokron]

That was the first thing I considered actually. /home/backup/ but cPanel has always recommended against having the backup in home. I am wondering if I would run into a backup loop as it archives all the contents of /home/.

The main problem this generates is all the backups you generate get counted towards your users' disk quotas.

I did not say inside /home/backup but outside /home.

[Solokron]

The partition set to fill the rest of the drive is set for /home.

There is no other way then.

You only have two options,
1) Setup /home/backup
2) Remove disk2 from the RAID and use it for backup.

 

[Solokron]

Nonsense, I am quite confident there is a way this can be done.

I should say, there is no *easy* way.
You still can resize your current partitions but that's way beyond from what I could recommend for a production server.

Well of course, if it was easy I woudn't have asked the question I may ultimately just dump the contents onto another server with the proper partition scheme setup and run an rsync via SSH. I am aware of the old rsync lines required for cPanel and accounts:

rsync -vrplogDtH /usr/local/apache/conf
rsync -vrplogDtH /var/named
rsync -vrplogDtH /home/*
rsync -vrplogDtH /usr/local/cpanel
rsync -vrplogDtH /var/lib/mysql
rsync -vrplogDtH /var/cpanel
rsync -vrplogDtH /usr/share/ssl
rsync -vrplogDtH /var/ssl
rsync -vrplogDtH /usr/local/cpanel/3rdparty/mailman
rsync -vrplogDtH /var/log/bandwidth
rsync -vrplogDtH /usr/local/frontpage
rsync -vrplogDtH /var/spool/cron
rsync -vrplogDtH /root/.my.cnf
rsync -vrplogDtH /etc/httpd/conf/httpd.conf

Is there anything new required for the newer versions? Is there an easier cleaner method maybe?

I am not the most confident in cPanel/WHM transfers. We have done them far too many times and there is always something it misses.

Does anyone have any input on this?

Thank you.

Thank you.

We have done it using below command:

rsync -az -e ssh /source path [email protected]:/otherserverpath

 

[Solokron]

Yes, that is how you would perform the rsync but that is not exactly my question.

I usually throw in a v for verbose myself.
