unknown filesystem type linux_raid_member

When i try mount a HDD, i get error

This is because the disk is part of RAID.

Lets check the disks avaialbe with parted -l

parted raid

parted shows /dev/sda1 and /dev/sdb1 as raid with same size. So its assemble raid array with command

I used /dev/md3 as other device names (/dev/md0, /dev/md1 and /dev/md2) are already in use.

Now you can mount this drive with command

Using tar over SSH Session

I wanted to make a tar of a folder on a remote server. But the server don’t have much disk space left, so the tar operation failed.

The server had no rsync installed to copy over the folder to another server.

To save generated tar file on another server, i used command

Example

See tar
