RNAS-1200 Series Managing Drives and Storage
7-2
Checking Drive Status, Capacity, and Health
To see an overview of the system’s drive stats, click on the DISK tab. On this page you may monitor the status,
temperature, usage information, and total capacity of the storage drives, as well as get a full S.M.A.R.T. report
on drive behavior. You may also perform low-level formatting and scanning of the drives.
WARNING
Only use the
Scan Disk
feature after carefully reviewing the manual page and the relevant command options.
The
Scan button will trigger the command #fsck –p –f across the entire drive
architecture. If used
improperly, or at the wrong time, this could seriously damage the logical file system and result in permanent
data loss. In RAID architectures it could potentially erase data or break the RAID. For a detailed overview of the
fsck
command, refer to the Linux fsck.ext4(8) man page, at http://linux.die.net/man/8/fsck.ext4.
The Format button will reformat your drives with a clean ext4 file tree. How the file tree is written across the
physical drives will depend on the architecture you configure under the RAID tab, Creating a Disk Volume.
IMPORTANT!
Formatting your drives will erase all data
. Before reformatting your
drives, make sure you have backed up
any important data.
