Resychronizing Or Recovering A Raid 1 Volume; Disk Replacement And Volume Labels; Creating An External Volume - ZyXEL Communications NSA-220 User Manual

6.6.1 Resychronizing or Recovering a RAID 1 Volume

Resychronizing or recovering a RAID 1 volume that was down is done block-by-block, so the
time it takes depends more on the size of your hard drive(s) than the amount of data you have
on them.
Do not restart the NSA while the NSA is resychronizing or recovering a volume
as this will cause the synchronization to begin again after the NSA fully
reboots.
You can access data on a RAID volume while it is resychronizing or
recovering, but it is not recommended.

6.6.2 Disk Replacement and Volume Labels

When you create a volume, the NSA writes the volume label to the disk.
Deleting a volume removes volume label information on its disk(s). It is
recommended that you first delete a volume before removing its disk(s).
If you do not want to keep the data on a disk that you will remove, it is recommended that you
delete the volume before you remove the disk. If you remove a disk(s) without deleting its
volume and you later put the disk(s) back in a different volume, you may have more than one
volume with the same name. For example, suppose you have two disks, Disk A and Disk B
and you create two JBOD volumes, volume1 (with Disk A) and volume2 (Disk B). Later you
remove Disk A and replace it with another disk, Disk C and you re-create volume1. (You did
not delete volume1 when you removed Disk A.) Later you replace Disk B with Disk A. Disk A
still retains the volume1 label, so at this point both Disk A and Disk C have the volume1 label.
Although you can still use the volumes, you may find the naming confusing.
