Hello I have the following problem. I have set up a Linux Software Raid 5 with 4 160GB Disks. This works well. Now i run out of Disk Space and want to add another 160 GB Disk on the fly. Is this possible without loosing Data? my /etc/raidtab raiddev /dev/md0 raid-level 5 nr-raid-disks 4 nr-spare-disks 0 persistent-superblock 1 parity-algorithm left-symmetric chunk-size 32 device /dev/hdi1 raid-disk 0 device /dev/hdj1 raid-disk 1 device /dev/hdk1 raid-disk 2 device /dev/hdl1 raid-disk 3 My system is a Debian/gnu Linux Woody Box. Installed is Raidtools2 and mdadm. I tried the raidreconf tool but always got an error message. Has anybody the same problem yet and has solved it, or can tell me a solution? cYa Dominik Sennfelder - 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
