antsle one, antsle one Pro, antsle one Ultra
antsle one XD, antsle one XD Pro, antsle one XD UltraBlue usb ports: usb 3.0.
Black usb ports: usb 2.0.
NOTE: You must change the boot options in the system BIOS after adding a USB device. Upon the next restart, the antsle will try to boot from the USB and fail. If you did not configure IPMI you can connect a keyboard and monitor to the antsle. Power up and hit <Del> at the SuperMicro splash screen to enter the bios settings. Arrow over to the 'Boot' menu and select 'USB Device BBS Priorities' and set the boot option to 'disable' for the usb device. Save settings and exit.
There are three main ways to utilize external USB drives with the antsle.
- Add Zpool storage
- Give an antlet exclusive access to a USB drive
- Mount USB storage in the edgeLinux file system
Create Zpool on External USB Drive
You can use additional external USB storage for antlets and virtual drives.
First ssh to the antsle
To see the existing drives run
The drives are named: sda, sdb...
Then plug in your usb drive and run 'lsblk' again to see the name of the new drive - it should be the last drive in the list.
Now we want to prepare the drive for zfs by removing the partitions on the drive. (This will destroy all data on the USB drive!).
parted -a optimal /dev/sdX
where 'sdX' is the name of your usb drive
Note: If 'parted' is not found, you can install it with the command:
emerge -av parted
this will warn, any data on the drive will be destroyed. If this is ok with you, answer Yes.
then quit 'parted'
Now lets create a zpool on the drive
zpool create POOL_NAME -m /POOL_NAME /dev/sdX zfs set atime=off POOL_NAME
Replace POOL_NAME with a name to easily identify this drive.
Replace 'sdX' with the actual drive name
POOL_NAME must be the same in each part of the commands. ex:
zpool create myusbdrive -m /myusbdrive /dev/sde zfs set atime=off myusbdrive
Now you can refresh antman and create a new antlet or virtual drive on this zpool. You will see your new zpool in the 'zpool' dropdown.
If you want mirrored usb disks repeat the 'parted' steps for the second drive but run the following zpool commands.
zpool create POOL_NAME -m /POOL_NAME mirror /dev/sdX /dev/sdY zfs set atime=off POOL_NAME
sdX and sdY need to be replaced by the actual drive names displayed in 'lsblk' Replace POOL_NAME with the desired zpool name
You do not need to update /etc/fstab. zfs will take care of mounting the zpool if the antsle is rebooted. Refresh antMan and you should see the new zpool.
Remove a zpool
At the antsle's command line list the zpools
Then destroy the zpool
zpool destroy POOL_NAME
Remove the directory the zpool was mounted to
rm -rf /POOL_NAME
Now if you refresh antman and try to create a new antlet, the zpool dropdown will no longer list the usb zpool.
USB Pass Through
USB Passthrough allows you to assign an external USB drive to a specific antlet.
Note: Currently USB Pass through only works with KVM antlets
Enter the antlet details page by clicking the name of the antlet
Then choose the 'USBs' tab and select your device.
Be sure to 'Stop' then 'Start' the antlet.
Mount USB in the edgeLinux file system
This can be useful to store installation .iso files or store backups of other files without filling up the root '/' partition. List the existing drives with the command:
The drives are named: sda, sdb... Find your device and partition number in the list. Crate a directory to mount the USB in
mkdir -p /mnt/usb1
Mount the USB
mount /dev/sdXN /mnt/usb1
replace 'sdXN' with the device(X) and partition number(N) with those of your USB as seen in the 'lsblk' command.
Note: If get an NTFS unknown file system error, you can install NTFS support with the command:
Check that you can see the files on the USB with
To make this mount persist after a reboot, we need to add the mount info to the 'fstab' file.
Again replace the device name with yours. I will use /dev/sdc1 in this example:
echo "/dev/sdc1 /mnt/usb1 ntfs noatime 0 2" >> /etc/fstab
To un-mount the USB (the command is 'u'mount not 'un'mount)
