I gave the VM Seafile runs on 2 terabytes of storage so I should not be out of storage space. I see /dev/mapper/cl_seafile-root is 100% full though. Why did this happen and what can I do to fix it?
Thanks in advance for any help provided. Always greatly appreciated.

btw. check your “df” command your root filesystem is full and “tmp” is a part of it.
P.S. : All your 2TB are assigned to “home” - I do not want to explain the the Linux filesystem in detail, but I would recommend you to assign all the space to “/” (root - not the root user) - that not a perfect solution but for you it would be the easiest way to solve your problem. Do not create separate partitions for “/boot” or “/home” - maybe you have to chose manual partitioning when you install Centos.
510719 was the highest number I could use. Now my df -h reads
My question is did I do this correctly? It looks ok based off of the very little linux I know (I’m a windows kind of guy) but I thought I would check with the experts. Looking forward to hearing back from you.
Hi,
I am not linux guru but you can do it like this…(maybe this is not the best way to do it )
df –h (show me filestructure)
Root is full. We want to increase root http://xmodulo.com/manage-lvm-volumes-centos-rhel-7-system-storage-manager.html
Switch off the machine (or VM) (optional)
add new hdd (e.g. new vdi or scsi …) (Add e.g. 3 TB)
restart VM
If we now enter the following in the console should the new HDD be visible.
ls /dev/sd*
New is sdb
Then install the System Storage Manager console
sudo yum install system-storage-manager
After that, check LV volume, standard in CentOS 7 installation uses LVM and XFS filesystem as default.
sudo ssm list
sudo ssm add -p centos /dev/sdb
(ADD disk to LVM Pool)
Increase by 50 GB (This can also be done several times!
sudo ssm resize -s+50GB /dev/centos/root
Check
You can add also more e.g. (if you added a 3TB Disk)
sudo ssm resize -s+2800GB /dev/centos/root
sudo ssm list volumes
For FS Size really get free you will enter the following. http://ask.xmodulo.com/expand-xfs-file-system.html
sudo xfs_growfs /dev/centos/root
Check with
sudo ssm list volumes
df -h
Yes, because you removed the home folder/LVM. Then extended the space on the root LVM but the home folder still is not there. You deleted all data of /home. Linux saves all user data in the home folder. I can imagine that without this home folder your system does not boot correctly. You should post this on a CentOS Forum, they can help you.
Generally you should always have a backup of your data before doing such things. I hope this is the case?
@BetaLeaf I am afraid this is not the right place to explain you in detail how to install a linux system.
There are many linux distributions you can choose from, I would recommend you to start with Ubuntu (as you did before), because it is a very popular system and it got a big community, where you can get help. If you do not know what LVM is (don’t use it if you do not understand it, because it makes thinks more complicated! - believe me, you do not need it for your kind of VM installation, keep things simple as possible for the beginning!), you should take some time to become familiar with the basic principle of linux.
Alright. I gave up the vm and just started fresh. I made sure my partitions were properly sized. I gave /home 10 gb. Wasn’t sure how much I should give it but I didn’t see myself or another software writing data to it. I gave / the rest.
sounds like its running properly now. I guess you already know: if you have installed seafile by using the default paths (by following the documentation), your files might be stored all into the /home folder. that means you might reach your seafile storage maximum at ~10gb. of course your partition(s) can be resized to overcome that limitation.
thanks a lot for sharing this hint. then you re surely not running into any storage problems;) I ve had to use https://manual.seafile.com/deploy/ since my apache multi configuration etc is more complex. interesting that the deployment dirs are different: /opt/seafile vs. /home/(user/)seafile. not a problem; just important to mention if some beginner doesnt know how to start… can be installed under theoretically any directory.
