Requirements for upgrading Ensim Control Panel
File system EXT3
Important: Quotas may not function as intended if you use other file systems.
Disk space At least 40 GB
Disk space partitioning:
/ 5 GB or more
(assuming minimum disk space of 40 GB)
/usr 5 GB or more
/swap Twice the size of RAM
The size of the partitions can vary in proportion to the size of the disk space.
/var 4 GB or more
/home 20 GB or more (depending on the number of sites you want to host)
Important: Do not create /home/virtual on a separate partition. The Site Administrator dashboard reports incorrect disk usage if the directory is created on a separate partition.
