Craptastic. Today (2016\/06\/26) another disc of my archive RAID5 failed (rotating, \u00a0SEAGATE ST3000DM001, Serial W1F245R4, out of warranty of course). When I opened the casing, I knew why. The drives were so hot (literally) that I almost burnt my fingers!<\/p>\n
Note to Self: Vacuum the thing once in a while. I seriously doubt that any air was flowing at all! Let’s hope that it’ll survive the resync. Only 18 hours to go, Yay!<\/p>\n
For the record: Hot-adding a disc to the array:<\/p>\n
# mdadm --manage --add \/dev\/md[x] \/dev\/sd[y]\r\n\r\n<\/pre>\nUpdate (2016\/06\/27 9:15am):\u00a0<\/strong>I guess I almost lost the array. The rebuild was progressing fine at 93% (about 6:00am) when one of the drives started to make clicking sounds. At first I tried to sit it out, but eventually I shut down the computer and let the drives cool off. That was a very wise\u00a0decision. 2 and a half hours later the rebuild is continuing with nominal speed and without clicking sounds.<\/p>\n
Fortunately, the Linux kernel leaned to continue a RAID rebuild some time ago if it’s shut down cleanly, so it didn’t start from scratch.<\/p>\n
Nevertheless, I ordered another spare drive. Seagate discs\u00a0used to be much more reliable \ud83d\ude41<\/p>\n
Update (2016\/06\/27 9:50am):\u00a0<\/strong>Had to shut it down again. One drive started acting up again. After a shower and a shave I fired it up again, this time with the front panel removed, so the air can circulate. Well, only 36 minutes to go, 98.1% done! Tomorrow 2 new drives will be delivered.<\/p>\n
Update (2016\/06\/27 10:45am):\u00a0<\/strong>Wow, this\u00a0has to be a very bad joke, and a\u00a0blessing in disguise. The rebuild didn’t finish, but fortunately the\u00a0failed\u00a0drive is\u00a0the one I just replaced! The array is still there, so I’m crossing my fingers that the remaining discs survive until DHL rings my doorbell tomorrow!<\/p>\n
Update (2016\/06\/29 10:30am):<\/strong> YES! The new drive is good, rebuild is done. Unfortunately failed new drive from the 27th is out of warranty \ud83d\ude41 Who would have guessed…<\/p>\n
Well, well, well… The story continues!<\/a><\/p>\n
