June 30, 20233 yr Greetings! I installed a 250G drive to test as a Cache device on a server. The disc 'appears' but isn't recognized in Unraid under the Main - Pool tab or in system devices and I'm not sure if that is because there is no partition created. The below is what I am seeing, under System Devices and under lsblk -f: root@unraid:~# lsblk -f NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS loop0 squashfs 4.0 7.5G 4% /lib loop1 squashfs 4.0 7.5G 4% /usr loop2 btrfs 88b02e85-3c6e-48ac-9849-0c1ba46bcb21 15.4G 22% /var/lib/docker/btrfs /var/lib/docker sda └─sda1 xfs 67212bab-f711-4718-a047-68fe17919120 sdb └─sdb1 vfat FAT32 UNRAID 272B-4CE1 7G 6% /boot sdc md1p1 3.6T 1% /mnt/disk1 The device isn't showing up under fdisk -l, probably due to the lack of partition: root@unraid:~# sudo fdisk -l Disk /dev/loop0: 59.3 MiB, 62177280 bytes, 121440 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 Disk /dev/loop1: 334.05 MiB, 350277632 bytes, 684136 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 Disk /dev/sda: 3.64 TiB, 4000752599040 bytes, 7813969920 sectors Disk model: easystore 25FA Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 7CBACB44-8BC8-4320-813C-E946FCD93175 Device Start End Sectors Size Type /dev/sda1 64 7813969886 7813969823 3.6T Linux filesystem Disk /dev/sdb: 7.45 GiB, 8004304896 bytes, 15633408 sectors Disk model: Cruzer 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: 0x00000000 Device Boot Start End Sectors Size Id Type /dev/sdb1 * 2048 15633407 15631360 7.5G c W95 FAT32 (LBA) Disk /dev/md1p1: 3.64 TiB, 4000752545792 bytes, 7813969816 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 No medium found: root@unraid:~# sudo fdisk /dev/sdc Welcome to fdisk (util-linux 2.38.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. fdisk: cannot open /dev/sdc: No medium found If the disc is dead, that's fine. I'm just trying to not throw it away if it can be saved. It might fail healthchecks but I can run that after I can get a partition on it, if that is the case. This disc won't be used for anything beyond testing as is. Just trying to test a new setup before I undo everything I already have setup. Edited June 30, 20233 yr by Trizzd remove personal data
