Hi all, while trying to substitute a failed disk, I'm using the command: # mdadm /dev/md1 --add /dev/ide/host0/bus1/target0/lun0/part6 but I get: mdadm: hot add failed for /dev/ide/host0/bus1/target0/lun0/part6: No space left on device What does it mean? I don't know how to interpret it. I thought it was the partition that is not same dime as the other one (disks are different) but the partition I'm adding is bigger... as you can see further on. I noticed that the 2 disks are not seen in the same way, as if the second is not in LBA mode: cat /proc/ide/hda/model MODEL: MAXTOR 6L040J2 GEOMETRY: cat /proc/ide/hda/geometry physical 77557/16/63 logical 4866/255/63 cat /proc/ide/hdc/model MODEL: Maxtor 6E040L0 GEOMETRY: cat /proc/ide/hdc/geometry physical 79656/16/63 logical 79656/16/63 ########### mdstat ########################################################## root@argo-cd root # cat /proc/mdstat Personalities : [raid1] read_ahead 1024 sectors md0 : active raid1 hdc1[1] ide/host0/bus0/target0/lun0/part1[0] 24000 blocks [2/2] [UU] md1 : active raid1 ide/host0/bus0/target0/lun0/part6[0] 2048192 blocks [2/1] [U_] md2 : active raid1 ide/host0/bus0/target0/lun0/part7[0] 36491520 blocks [2/1] [U_] unused devices: <none> ########### fdisk - parted ################################################## And here are the partition tables of the disks: root@argo-cd root # parted /dev/hda print Disk geometry for /dev/ide/host0/bus0/target0/lun0/disc: 0.000-38172.750 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 23.532 primary ext2 raid 2 23.533 38170.063 extended lba 5 23.563 533.408 logical linux-swap 6 533.439 2533.688 logical reiserfs raid 7 2533.720 38170.063 logical reiserfs raid root@argo-cd root # parted /dev/hdc print Disk geometry for /dev/ide/host0/bus1/target0/lun0/disc: 0.000-39205.687 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 23.625 primary ext2 raid 2 23.625 39205.687 extended lba 5 23.656 533.531 logical 6 533.562 2536.242 logical raid 7 2536.273 39205.687 logical raid Thanks in advance sandro *:-) -- Sandro Dentella *:-) e-mail: sandro.dentella@tin.it http://www.tksql.org TkSQL Home page - My GPL work - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
