Nc-format-USB will format your external USB drive to BTRFS, with the given Label.

Configure Swap on the USB drive (optional).

Configure Database data to be on the USB drive (optional).

Configure Nextcloud data to be on the USB drive.Format USB drive (optional but check note).For instance, if the label of the drive is mylabel then use the path /media/mylabel for items such as nc-datadir, nc-database and so on. Important note: If you are using only one USB drive, you can leave the default path /media/USBdrive for all configuration options, but if you are going to use more than one you need to reference them by label, or NCP will not be able to know which one is which. To re-connect it, such that it appears now in the mount table.This guide will help you configure an external USB drive. Next, I formatted the partition: $ sudo mkfs.ext4 /dev/sda1 Calling ioctl() to re-read partition table. Selected partition 1 Partition 1 has been deleted. To create the partition I used fdisk by invoking sudo fdisk /dev/sda the interactive session is easy to follow : Command (m for help): d EXT4-fs (sda1): Remounting filesystem read-only EXT4-fs error (device sda1): _ext4_journal_start_sb:62: Detected aborted journal EXT4-fs warning (device sda1): _ext4_read_dirblock:908: error reading directory block (ino 2, block 0) JBD2: Error -5 detected when updating journal superblock for sda1-8. lost page write due to I/O error on sda1 Buffer I/O error on device sda1, logical block 121667584 sd 12:0:0:0: Assuming drive cache: write through scsi 12:0:0:0: Direct-Access Generic External 2.10 PQ: 0 ANSI: 4 usb-storage 1-1.2:1.0: USB Mass Storage device detected usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Here is the output from dmesg usb 1-1.2: New USB device found, idVendor=13fd, idProduct=1340 My disk is now moved to sdb1 and if I try to mount sdb1 the same errors happen and the disk reappear under sda1. The other thing that happens in that if I do a fdisk -l I will get this now: Device Boot Start End Blocks Id System If I do a ls /mnt/external1 I get the following error: ls: reading directory /mnt/external1: Input/output error then I mount the drive by mount /dev/sda1 /mnt/external1ДЄnd this takes a little while but it returns with no error.

dev/sda1 2 1953525167 976762583 83 LinuxДЄnd this runs and does what it does without any erros. This is what I do: fdisk -lДЄnd the result is Device Boot Start End Blocks Id System The USB drive works fine if it is formatted in FAT but if I format the drive in ext4 the drive does not mount correctly and it gives me all sorts of error.

I have a Raspberry PI to which an external 1T hard drive is attached by USB.
