DESCRIPTION
The vblade-persist script is used to show and manipulate persistently-exported ATA-over-Ethernet devices. It has a simple subcommand syntax.Persistent AoE device exports can be configured to come up at boot time. For each running persistent AoE export, a symlink pointing to the backing device is created in /dev/etherd/, mirroring the devices seen by clients of the AoE device.
MANAGEMENT SUBCOMMANDS
ls [--noheader]
vblade-persist ls shows all existing persistent AoE exports. The columns of the output are, in order: AoE Shelf, AoE Slot, Network Interface, Backing Device, AutoStart, Status. AutoStart is either "auto" (start automatically at boot), or "noauto" (don't start automatically at boot). Status should be either "run" (running) or "down" (not running).
The optional --no-header argument suppresses the header line. This may be convenient for machine-parseable output.
setup
shelf slot netif source
vblade-persist setup
creates a new persistent exported AoE block device. You must supply
all four additional arguments. These are the same arguments supplied
to
vblade(8).
You should specify
source
using an absolute path.
New devices set up this way are noauto (not brought up automatically at boot) and down (not exported immediately).
destroy
shelf slot
vblade-persist destroy
halts any running exported AoE block device managed by
vblade-persist
and removes the service directory used to manage it.
start
shelf slot
stop
shelf slot
restart
shelf slot
These commands control a specific exported AoE device. Instead of
specifying
shelf
and
slot
, you can also provide the special keyword
all
which will act on every exported AoE device.
auto
shelf slot
noauto
shelf slot
These commands control whether a specific exported AoE device should
be started automatically (
auto
) or not (
noauto
) at system boot time. Instead of specifying
shelf
and
slot
, you can also provide the special keyword
all
which will act on every exported AoE device.
MAC-ADDRESS FILTERING
You can use vblade-persist to restrict access to specific exports by MAC address, using the mac subcommand.
mac shelf slot ls
List all MAC addresses allowed to access the specified device, one per
line. If the list is empty, no MAC address limits are imposed on this
device.
mac shelf slot clear
Remove all MAC address filtering from the specified device. No MAC
address limits will be imposed on this device.
mac
shelf slot
add
[ addr ... ]
Add a MAC address (or more than one) to the list of allowed addresses
for the specified device. Note that if there were no MAC addresses
listed previously, this will enable MAC address filtering for the
device.
mac
shelf slot
del
[ addr ... ]
Remove a MAC address (or more than one) from the list of allowed
addresses for the specific device. Note that if you remove all the
MAC addresses from the list, this will disable MAC address filtering
for the device.
EXAMPLES
Set up /dev/sda2 as shelf 2, slot 3 on the network served by interface eth0. Make sure it starts automatically at boot, and start it up now:
vblade-persist setup 2 3 eth0 /dev/sda2
vblade-persist auto 2 3
vblade-persist start 2 3
Limit that same export to MAC addresses aa:bb:cc:dd:ee:ff and 11:22:33:44:55:66:
vblade-persist mac 2 3 add aa:bb:cc:dd:ee:ff 11:22:33:44:55:66
Remove all MAC address restrictions on the same export:
vblade-persist mac 2 3 clear
BUGS
You can't currently use the vblade-persist framework to export a device (or two) with the same shelf/slot identifier on two different network interfaces.
DEPENDENCIES
The exports themselves are handled by vblade(8). Supervision of the exports and convenient management is enabled by runsv(8), from the runit suite.
