-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi,
I'm running Squeeze under raid 1 with mdadm. One of the raid failed and I replace it with space I had available on that same disk. Today, when rebooting I got an error cause the boot flag was still on both partitions(sdb1 and sdb3 below). I used the rescue part of the debian installer CD to remove the boot flag with fdisk, and now everything is working. My question is what to do with the dead raid partition on that disk (sdb1 and sdb2 below)? Can I safely delete them and mark them unusable or similar? Below are some details about the system. /dev/sdb is 250G; I had an sdb1 and sdb2 failure. I created sdb3 and sdb4 and add them to the array. They are the current member of the md array. /mett# uname -a Linux asus 3.2.0-0.bpo.4-686-pae #1 SMP Debian 3.2.57-3+deb7u2~bpo60+1 i686 GNU/Linux root@asus:/home/mett# root@asus:/home/mett# mdadm --detail /dev/md1 /dev/md1: Version : 1.2 Creation Time : Mon Feb 4 22:46:04 2013 Raid Level : raid1 Array Size : 97654712 (93.13 GiB 100.00 GB) Used Dev Size : 97654712 (93.13 GiB 100.00 GB) Raid Devices : 2 Total Devices : 2 Persistence : Superblock is persistent Update Time : Sun Oct 26 12:03:37 2014 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Name : asus:1 (local to host asus) UUID : 639af1ab:8ec418b5:8254ef0d:ad9a728d Events : 75946 Number Major Minor RaidDevice State 2 8 2 0 active sync /dev/sda2 3 8 20 1 active sync /dev/sdb4 (/dev/md0 is same structure as above with sda1 and sdb3 as raid members) root@asus:/home/mett# Disk /dev/sdb: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00066b3e Device Boot Start End Blocks Id System /dev/sdb1 1 64 514048+ fd Linux raid autodetect /dev/sdb2 65 12515 100012657+ fd Linux raid autodetect /dev/sdb3 * 12516 12581 530145 fd Linux raid autodetect /dev/sdb4 12582 25636 104864287+ fd Linux raid autodetect Command (m for help): Thanks a lot in advance. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iF4EAREIAAYFAlRMaDMACgkQGYZUGVwcQVJTNQEAtTFXt5o+TJUA6v7XQiUL1MCQ f24zTUpe7Zqrcz6XLi4BAJNEuPRx8QFZZeSHK9f1Qg/zAHhXBVTn3G21ODgEp+XQ =eaQS -----END PGP SIGNATURE-----
