You have been subscribed to a public bug: There's a scary issue with fstrim on raid0 and raid10 mdadm devices. It is fixed upstream in linux/4.1.5-1, linux/3.16.7-ckt17-1, but I can't find anything in the changelogs for ubuntu.
Here's the links: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=793326 http://www.spinics.net/lists/raid/msg49440.html I did my amateur analysis by extracting sources for current trusty kernel 3.13.0-65-generic and current trusty-lts-utopic 3.16.0-50-generic and looking at files referenced in patches from the Martin K. Petersen's email, and it appears that 3.16 already has this fix included, and 3.13 is a completely different code base, so it isn't clear whether it is affected or not. I've disabled fstrim in cron until I understand the situation better. Could someone knowledgeable chime in on the status of this on Ubuntu, specifically Trusty and after? ** Affects: linux-meta (Ubuntu) Importance: Undecided Assignee: Joseph Salisbury (jsalisbury) Status: New ** Tags: bot-comment -- Potential raid0 data corruption when using trim https://bugs.launchpad.net/bugs/1507618 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
