Resolved Change backup location in Linux

[Marcel Caspar]

Hello,


I could not find any thread that is targeting my issue.

I changed the backup location of my backups in /etc/psa/psa.conf to a mounted storage, according to this tutorial.

After that I started a new manual backup job via the web interface and got the following error "Der Backupvorgang ist fehlgeschlagen: Not enough free disk space to backup selected objects. At least 3166.8235733 MBytes free disk space is required."

My configuration:
DUMP_D /mnt/block-storage/plesk_backups
DUMP_TMP_D /mnt/block-storage/plesk_backups_tmp

Both directories are owned by psaadm

On my main partition are 1.6GB diskspace available. On /mnt/block-storage/ are 56G available

I am confused why my backups job is failing, since I moved the backup location and the temp backup location on a disk that has enough diskspace available.

Setup:
Version 17.8.11 Update #10
Debian 8.10‬

Please check that this solution works for you How to change the location for Plesk backups on Linux

 

[Marcel Caspar]

Thank you for your reply

I followed the exact tutorial as I said in my previous post

 

[IgorG]

In this case, we need more detail of this issue. At least part of backup logs with related error messages.

Hope it's okay when I paste this just as text. Could not upload a .log or .txt file

[IgorG]

It seems that location of DUMP_TMP_D as /mnt/block-storage/plesk_backups_tmp is not taken in account for some reasons. Try to find mentions of this variable in backup logs.
@DenisG could you please assist here?

 

[DenisG]

We need content of /etc/psa/psa.conf.

I will try to increase the log level and see where the variable DUMP_TMP_D is mentioned, as Igor said. In the current logs, there are no occurences of it.

 

[DenisG]

I am sorry but I cannot reproduce the issue. It looks like nothing is mounted at '/mnt/block-storage' and we see free space at '/'.

 

[Marcel Caspar]

I've double checked the mount point, it's mounted and the user psaadm has read and write permissions

tested it with: (for /mnt/block-storage/plesk_backups and /mnt/block-storage/plesk_backups_tmp)

• Changed the shell for psaadm from /bin/false to /bin/bash in /etc/passwd
  
• su psaadm
• nano myFile
• cat myFile
• undone changes in /etc/passwd

I see now, that mysql backups are made and saved in /mnt/block-storage/plesk_backups
Latest is from this morning

Before I opened this Thread, I upgraded my Plesk instance to 17.8.11. My initial error was already thrown on my previous version , but I hoped it was fixed in the latest relase.

And it seems to me, that Plesk created successfully a backup before the upgrade. In /mnt/block-storage/plesk_backups.

 

[DenisG]

Could you run the commands

/usr/local/psa/bin/python -c "import os,statvfs; stats=os.statvfs('/mnt/block-storage/plesk_backups'); print stats[statvfs.F_BSIZE]*stats[statvfs.F_BAVAIL];"

df -h

It is mounted, yes. But it's mounted to /mnt/block-storage/archive and not to /mnt/block-storage. That was my fault that I did not saw.
I changed the moint point to /mnt/block-storage and ran a manual backup job nor errors. Also the scheduled backups are also running perfectly. Thanks!


I'm very thankful for your fast, friendly and helpful support!
