Some operations on file system (subdomain creation, file uploads etc) are failed:
Plesk log shows the following error:
System error 122: Disk quota exceeded Cannot create directory /test.example.com: Disk quota exceeded
The problem is caused by a quota limit set for the FTP user of the main domain.
- Quota for FTP user in Plesk > Domains > example.com does not correspond user quota on system.
Example: Quota is set to unlimited for FTP user in Plesk > Domains > example.com, but quota is different on the system:
# quota -v exampleuser Disk quotas for user exampleuser (uid 10277): Filesystem blocks quota limit grace files quota limit grace /dev/root 2131452* 0 2097152 786 0 0
Change/update FTP user quota in Plesk > Domains > example.com > FTP access.
