Abstract: Examples described herein relate to method and system for managing write modes of a filesystem, wherein the filesystem is mapped to a thinly-provisioned virtual volume (TPVV) defined using a common-provisioning group (CPG) of a set of physical storage devices. The filesystem may be operated in a read-write mode. A used storage capacity of the CPG may be monitored when the filesystem is operational in the read-write mode. Further, a check may be performed to determine whether the used storage capacity of the CPG has reached a storage fullness threshold value. Accordingly, if it is determined that the used storage capacity of the CPG has reached the storage fullness threshold value, the filesystem may be transitioned to a partial read-only mode from the read-write mode.
