Change DataStore Location
Wanos offers the option to modify your DataStore location by switching partitions, physical disks or USB drives/sticks.
How to change DataStore Location
1. Determine your new partition or drive by running:
fdisk -l
In this example, a new disk called sdb has been added.
2. Run the following commands in the exact order:
/tce/etc/wanos/wanos-fdisk sdX
Replace "X" in sdX with the correct letter of the target drive. In this example, b was used = sdb.
reboot
mkfs.ext3 /dev/sdX1
Replace "X" is sdX1 with the corect letter of the target drive. In this example, b was used = sdb1.
reboot
3. Set the DataStore in Wanos web UI. Configure > System Settings In this example, sdb1 was used.
Scroll to the bottom part of the page, click the Submit button, click OK on the dialog box and Wanos will reboot.
