Hi list, I'd like to know how can I add disk space to RAID 1+0 volumes. I have 4 disks of 1.5 TB. I've seen that I can increase size of gmirror volumes if I remove (from the volume) 1 disk, insert a new one. Once the sync is complete destroy the mirror volume, increase the size with fdisk then build a new mirror volume. Is it correct ? No problem with the metadatas (I don't think as they are totally recreated) ? But I can't find information on how to do this with stripes. I understand that it is more difficult as RAID 0 needs disks of the same size. If I use the same methodology, does the destroy/recreate metadata will make the datas stored lost ? If yes, can I do it ? Is there some documentation I didn't put my hand on somewhere ? Thank you for your help. -- Bastien Semene Administrateur Réseau& Système Cyanide Studio - FRANCE
