Thecus N4200 User Manual

72
With RAID level migration function, it has two different type “On line” and “Off line”
alone with limitation as listed below.
1. During RAID level migration, it is not allowed reboot or shutdown system.
2. Off line RAID level migration, all services will stop and data is inaccessible.
3. To have ZFS file system created doing on line RAID level migration from R1
to R5 or R1 to R6, the all services will restart and volumes “user data”
and “iSCSI” are read only during operation.
4. To have ext3 and XFS file system created doing on line RAID level
migration from R1 to R5 or R1 to R6, the all services will restart and
volumes “iSCSI” is read only but “user data” is capable read / write during
operation.
NOTE
Migrating a RAID volume could take several hours to complete
