10.1. About group disk capacity

The capacity of the group disk is limited by both total file size and the number of files (inodes) under them. For each 1TB unit of file size purchase, 2,000,000 inodes will become available.

The group disk status is reset once at the end of the fiscal year, and all group disks are in a grace state that can only be read and deleted.

The grace state lasts until mid-April, and unpurchased group disk space will become inaccessible after the grace period ends. It is necessary to purchase the group disk for the current fiscal year to continue using.

Also, group disk data will be deleted at any time after the grace period.
