Answering my own question, you can use the undocumented parameter 'unit' to set
the units to bytes in parted.
r...@storage:~# parted /dev/mapper/storagevg0-ntserveriscsi unit B print
Disk /dev/mapper/storagevg0-ntserveriscsi: 1099511627775B
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name
Flags
1 17408B 134235135B 134217728B Microsoft
reserved partition msftres
2 134235136B 1099510596607B 1099376361472B ntfs Basic data
partition
Information: Don't forget to update /etc/fstab, if necessary.
r...@storage:~# losetup -d /dev/loop2
r...@storage:~# losetup -o 134235136 /dev/loop2 /dev/storagevg0/ntserveriscsi
r...@storage:~# mount -t ntfs-3g /dev/loop2 /mnt/storage/
Just for the archives. Thank you, you've been a great help as always :)
