units, click the link next to the stop icon located below the Legend list.
Replacing Drives
Should a drive fail (solid red LED), it can be replaced (hot-swapped) without shutting down
the SnapScale node. If a spare is available on a node that doesn’t already have an active
member of the failed drive's peer set, the spare automatically replaces the failed drive and the
new drive being installed automatically becomes a spare. If no spares are available, the new
drive automatically becomes a member of the failed drive’s peer set.
A failed drive can be removed and replaced anytime. When hot-swapping multiple drives, it is
recommended to swap one drive at a time to avoid timing issues.
