Hi, I would like to request for two features of the Linux RAID subsystem to be integrated into webmin. 1) It would be very nice to be able to assign GLOBAL spares to RAID devices. GLOBAL spares are spares which are shared among RAID devices. This is now made possible with the 'spare-group' option in the mdadm.conf file. Having disks in the same spare-group shares them among raid devices. Very handy in my opinion. 2) It is not possible to add unpartitioned disks as RAID disk inside the RAID Module at this moment. You first have to create a partition (Linux RAID) on each disk for the module to see them as usable disks. The real big advantage for not having to use partitions is performance. Unpartitioned raid devices perform better then partitioned one because the partition breaks the alignment of the disks. Kind regards, Caspar Smit |

That's a nice idea, although sadly my test systems don't have enough disks
at the moment for me to develop this! Patches are welcome though.

Unpartitioned raid devices perform better then partitioned one because the
partition breaks the alignment of the disks.
Cool, I didn't know this was possible - support for it will be in the next
Webmin release.

Patches are welcome though. I can give you root / remote access to one of our test systems with debian 5.0 and webmin 1.480 (clean install) on it if you like. The system has 12x 500Gb disks to play around with. Let me hear if I should setup that for you.

That would be great! Even better would be a sample mdadm.conf showing the
kind of config you'd like Webmin to be able to create, as I haven't used
global spares before ..

BTW, how would you do a surface test of such a partitionless disk if you suspect problems?! PAT |
