I just purchased 2 new drives to add to a RAID5 and RAID6 array, respectively. I have already added the 8th drive to the RAID5 array and begun the growth. The critical phase has been completed. For safety, I umounted the array before I started the growth processs. At the rate the data is being read and written to the drives, the resync is going to take a very long time - about 4 days. I'd rather not have the array down that long, unless it's really necessary. Is there any greater amount of jeopardy to a RAID5 array during the growth (once the critical phase is complete) than under ordinary circumstances? That is to say, will losing a drive during the resync wreak havoc on the data? Once I am done upgrading the RAID5 array, I'm going to add a drive to the RAID6 array. 'Same question, there. Will the loss of 2 drives during the resync cause a loss of data? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
