The third drive was synced into the array with the above command.
But, now I am wondering what put it into read-only mode. Looking at man mdadm and greping for "read" I find nothing that says it goes into read-only mode by default. The only thing I can find relative to read-only operation and "create" mode is "--readonly start the array readonly -- not supported yet". Otherwise, read-only seems only to be available in "misc" mode. What I am ultimately after at this stage in the server building game is to ensure myself that the ide expansion cards I am using are not faulty. As I mentioned in another post, I had many many h/w problems with a previous attempt at raid building. I am using, apart from one new DIMM, entirely used parts whose history is unknown. I managed to find problems with the previous motherboard, two DIMMs, and I am not yet entirely sure of the integrity of the expansion cards. Do you know if read only mode could be caused by some fault in the cards? Thanks, will -- whollyg...@letterboxes.org -- http://www.fastmail.fm - mmm...
