repost with different subject, previous subject line suggested this was an answer, not a question. I have a drive marked as spare that I know is a synced member of a raid5. I want to add it back into the array *without* a reconstruct, i.e. just mark it as active and change it's position. How do I do that? Force assembly seems to just change the update time and mark as active, but I don't know what it will do about the position. On the other hand, hot add would change the postion of the drive, but, I expect, launch a reconstruct I don't want. As a last resort, I have lde installed and I'm prepared to use it. Background: I had a 'soft' error on one drive of a four drive raid5. I know now that I could have forced the assembly, but at the time chose to raidhotadd the existing drive. At the end of the reconstruct, /proc/mdstat presented me with a two drive failure! One of the other drives now had an earlier update time and was marked dirty, no-errors, seemed to be fine otherwise. The drive that reconstructed was up to date, but was marked spare and therfore no longer in the array. The first step I took to recover was to force the assembly with three drives - all but the drive marked spare. That seemed to work fine and I can mount the array. Now, of course the spare is out of date, but also out of position. redhat 9, mdadm 1.3, a raidtab, and no mdadm.conf Bill. - 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
