An inode is a record in a disk table which contains information about a
file/folder such as its size, owner, device node, socket, pipe, etc.
except data content and file name.
The number of inodes you use represents the number of files/folders you have on your webhosting account.
When a file is opened, the file’s inode is read by the kernel. The
more files/folders you have, the more inodes you use. And the more
inodes you use, the more system resources your account consumes.
In order to preserve the stability of the shared hosting servers we
have set limitation for the number of inodes per hosting account. Bear
in mind that if you run out of inodes, your account may be excluded from
the backup system or you may experience problems with file uploading
and opening your website.
