I've pulled the TSR and submitted SR1038301301 for dispatching a replacement SSD to eqiad. This is now over to Chris for receipt and installation/return of defective SSD. Since the failing SSD is currently working, we need to attempt to securely erase it before sending back to Dell. The directions for using hdparm are documented on https://wikitech.wikimedia.org/wiki/Dc-operations/Securely_Erasing_Media and I've checked, wdqs1009 has hdparm installed within the OS. I'm not sure how well a system will handle hdparm secure erase on 1 of 4 disks in a sw raid10, but this seems like an excellent opportunity to find out! I'm willing to remotely assist as needed! I would recommend this system be depooled during the SSD swap, in case the secure erase (only lasts 3 minutes) causes undue loads. @gehel: Are there directions for [de/re]pooling of wdqs servers we can follow for this within #dc-ops <https://phabricator.wikimedia.org/tag/dc-ops/>?
