Trying to install a RAID1 on a debian stretch, I made some mistake and got this, after installing on disk1 and trying to add second disk : root@server:~# fdisk -l Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x2a799300 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 3907028991 3907026944 1.8T 83 Linux Disk /dev/sdb: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x9770f6fa Device Boot Start End Sectors Size Id Type /dev/sdb1 * 2048 3907029167 3907027120 1.8T 5 Extended And : root@server:~# btrfs fi show Label: none uuid: eed65d24-6501-4991-94bd-6c3baf2af1ed Total devices 2 FS bytes used 1.10GiB devid 1 size 1.82TiB used 4.02GiB path /dev/sda1 devid 2 size 1.00KiB used 0.00B path /dev/sdb1
I think your problem is that sdb1 is a extended partition and not a primary one or you'll need to make a logical partition inside the extended partition and use that. -- Kai Stian Olstad
