Samsung Finds, Fixes Bug In Linux Trim Code

Posted by timothy on from the way-it-should-work dept.

New submitter Mokki writes: After many complaints that Samsung SSDs corrupted data when used with Linux, Samsung found out that the bug was in the Linux kernel and submitted a patch to fix it. It turns out that kernels without the final fix can corrupt data if the system is using linux md raid with raid0 or raid10 and issues trim/discard commands (either fstrim or by the filesystem itself). The vendor of the drive did not matter and the previous blacklisting of Samsung drives for broken queued trim support can be most likely lifted after further tests. According to this post the bug has been around for a long time.

    Confirmation bias. It was happening with other brands, but for one reason or another, people focused in on Samsung as the culprit, and once that happened, there was no getting out of it.

    The firmware bug of Samsung drives, a very severe one actually, was confirmed by Samsung. The RAID 0 issue is a totally different one, hardly affecting anyone.

    So yes, the severe issue was a bug on Samsung side, thile the very rare RAID 0 bug is Linux kernel one.
