May 22, 201313 yr OK, so long story short, I wanted to upgrade an old 1.5 GB drive to 3 TB. I pre-cleared the drive and everything was good, so I stopped the array, replaced the drive and started the array telling it I want to do it and to rebuild the data and expand. All this without actually powering off. The array cam online orange dot like it was re-building but I saw no status so I thought it was not doing anything because the other drive was still there. So, I stopped the array and wanted to put back the original till I could actually power off and replace. However, now the 1.5 is not large enough and can't be put back. If I start the array with the 3TB it says it will be unprotected and I have no option to rebuild the data. I have a second new 3TB drive I could put in there and if I do it shows the option to rebuild and expand, but before I mess something up, I thought it safer to leave the array offline and ask... Thanks. running 5.0 RC12a
May 22, 201313 yr Start the array with no disk assigned to the slot. Then it should allow a rebuild on any 3T drive.
May 22, 201313 yr Author should I start with no disk, then stop, add disk and rebuild? confused how I will re-build with nothing assigned...
May 22, 201313 yr #1 rule here: BE VERY CAREFUL or you'll lose data. At this point you really have no idea of the state of the 3TB drive, so I'd do the following: [Note that this requires running "at risk" while parity is calculated] (a) Save the complete contents of your flash drive, just in case (b) Write down the serial # of your parity drive (from the Web GUI) © SHUT DOWN (d) Replace the 1.5TB drive (e) Boot to the Web GUI, and do a NEW CONFIG (On the Utils page). Be CERTAIN that you assign the correct drive as parity -- if you do this wrong, you'll lose all of the data on the drive you assign as parity. ... Wait for parity to compute. Note that while this is being done, you're "at risk" -- i.e. any drive failure could result in data loss. (f) Run a parity check to confirm the parity computations were successful. NOW you can Shut down and replace the 1.5TB drive with the 3TB drive; then boot up and let it rebuild onto the larger drive.
May 23, 201313 yr Author BAH! Things were working there for a few hours... May 22 20:11:11 Tower kernel: md: disk3 write error, sector=4414767104 So, the question now would be, do I assign my other 3 TB drive to here and re-build? Then, pre-clear this one again to be sure it is not bad? syslog-2013-05-22.zip
May 25, 201313 yr Author OK, so I guess when you are dealing with terabytes of data you panic when things arent going right. In this case I know I did as opposed to realizing I had been through this before... Disable all add-ons reboot, expand, done... http://lime-technology.com/forum/index.php?topic=25075.0
