June 3, 20197 yr Hey Have used unRaid for a while, Linux for quite some time longer than that. Had the unfortunate issue of two drives at the same time getting read errors enough for me to pull them out of my unRaid system. Drives are formatted in XFS, both are data drives, one is a 1.5TB the other a 1TB, both removed after a clean shutdown and following removing drives from the unRaid FAQ. Now to the problem, reading these drives... I've tried several distros of Linux (I run a few, mostly Debian based). But I cannot get these drives to even mount. I'll take read-only as I just need to get the files off the drives. Ignore the "Seagate Expansion Desk" that's just my shucked USB enclosure. I get the same output (except for the drive size) from both drives. Here are the outputs from Ubuntu 19.04: dmesg -t Quote scsi 33:0:0:0: Direct-Access Seagate Expansion Desk 0604 PQ: 0 ANSI: 6 sd 33:0:0:0: Attached scsi generic sg2 type 0 sd 33:0:0:0: [sdb] 244190645 4096-byte logical blocks: (1.00 TB/932 GiB) sd 33:0:0:0: [sdb] Write Protect is off sd 33:0:0:0: [sdb] Mode Sense: 4f 00 00 00 sd 33:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 33:0:0:0: [sdb] Optimal transfer size 268431360 bytes sdb: sdb1 sdb: p1 size 15628200832 extends beyond EOD, enabling native capacity sdb: sdb1 sdb: p1 size 15628200832 extends beyond EOD, truncated sd 33:0:0:0: [sdb] Attached SCSI disk fdisk -l Quote Disk /dev/sdb: 931.5 GiB, 1000204881920 bytes, 244190645 sectors Disk model: Expansion Desk Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 268431360 bytes Disklabel type: dos Disk identifier: 0xd5cc9ac8 Device Boot Start End Sectors Size Id Type /dev/sdb1 64 1953525167 1953525104 7.3T 83 Linux Any help would be great, otherwise I'd have to start the long process of forensic carving to retrieve some of my files.
June 3, 20197 yr Community Expert By "removing drives following the FAQ (wiki?)" do you mean the rebuild parity method? Or do you mean the clear while maintaining parity method? The usual thing would have been to keep them in the array and repair the filesystem. Have you tried xfs repair where you have them now?
