It's only 250GB from what I can see - getting your hands on a 500GB or 1TB drive shouldn't be hard, and a quick stream of the partition shouldn't take long (although a "cp -a" might be safer, given that LUKS is involved ...). > > > > Cheers, > > Wol > > Thank you for the link, here is the output from the various packages listed on that page: > > uname -a > > Linux tsp520c 3.10.0-1160.2.2.el7.x86_64 #1 SMP Tue Oct 20 16:53:08 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux > > mdadm --version > > mdadm - v4.1 - 2018-10-01 > > smartctl --xall /dev... > > I skipped this since the output is lengthy and not sure which parts we might need. > > mdadm --examine /dev/sdb (and /dev/sdc as well as individual partitions) > > [root@tsp520c ~]# mdadm --examine /dev/sdb > /dev/sdb: > MBR Magic : aa55 > Partition[0] : 500118191 sectors at 1 (type ee) > [root@tsp520c ~]# mdadm --examine /dev/sdb1 > /dev/sdb1: > MBR Magic : aa55 > Partition[0] : 1701978223 sectors at 1948285285 (type 6e) > Partition[3] : 441 sectors at 28049408 (type 00) > [root@tsp520c ~]# mdadm --examine /dev/sdb2 > mdadm: No md superblock detected on /dev/sdb2. > [root@tsp520c ~]# mdadm --examine /dev/sdb3 > mdadm: No md superblock detected on /dev/sdb3. > [root@tsp520c ~]# > > [root@tsp520c ~]# mdadm --examine /dev/sdc > /dev/sdc: > MBR Magic : aa55 > Partition[0] : 500118191 sectors at 1 (type ee) > [root@tsp520c ~]# mdadm --examine /dev/sdc1 > /dev/sdc1: > MBR Magic : aa55 > Partition[0] : 1701978223 sectors at 1948285285 (type 6e) > Partition[3] : 441 sectors at 28049408 (type 00) > [root@tsp520c ~]# mdadm --examine /dev/sdc2 > mdadm: No md superblock detected on /dev/sdc2. > [root@tsp520c ~]# mdadm --examine /dev/sdc3 > mdadm: No md superblock detected on /dev/sdc3.
