Dead volume after disc replacement
Hello, I'm using ReadyNAS 2100 v1. Firmware: RAIDiator 4.2.30. RAID level X-RAID2, 4 disks of 3Tb. Disk 1 was dead, and disk 4 had increasing SMART errors. Before replacing disk 1: Disk 1 -- 2794 GB, Dead Disk 2 -- 2794 GB, Ok Disk 3 -- 2794 GB, Ok Disk 4 -- 2794 GB, Ok Logs also showed SMART errors on disk 4. I replaced disk 1. After replacing disk 1: Volume Status: Dead. This volume is no longer available. Disk 1 -- 2794 GB, Spare Disk 2 -- 2794 GB, Ok Disk 3 -- 2794 GB, Ok Disk 4 -- 2794 GB, Dead Last log entries are: - RAID sync started on volume C. (it started five days ago and hasn't finished) - Data volume will be rebuilt with disk 1. Kernel.log and system.log shows continously: ... Mar 17 19:12:32 NAS-xxx kernel: EXT4-fs (dm-0): previous I/O error to superblock detected Mar 17 19:12:32 NAS-xxx kernel: Buffer I/O error on device dm-0, logical block 0 Mar 17 19:12:32 NAS-xxx kernel: lost page write due to I/O error on dm-0 Mar 17 19:12:32 NAS-xxx kernel: EXT4-fs error (device dm-0): __ext4_get_inode_loc:4758: inode #80347898: block 1285554255: comm proftpd: unable to read itable ... I suppose if 2 disks have failed simultaneously, data might have lost. But: 1.- Is there any possibility of recovering any data? 2.- Should I replace Disk 4 before doing anything else? 3.- Should I perform a factory reset? Any advice appreciated. Thank you very much.Solved4.4KViews0likes4Comments
