    válasz Emperor_ #29815 üzenetére

    "A 850 PRO sem rossz választás, egy ismert probléma van vele, ami linux alatt jön elő." - Nem linux, Ubuntu. Egyébként egyre mesésebb a dolog, itt a legfrissebb bejegyzés, ez alapján pont olyan gyakori mint a lottó ötös teliholdnál, félszemű macska nyávogásával vegyítve.

    UPDATE July 13:
    Since the last update of this blog-post, we have been in a cooperation with Samsung trying to help them find the issue, during this investigation we agreed with Samsung to do not communicate until their agreement.

    As the issue was not reproduced on our server in Singapore, the reproduction is now running under Samsung supervision in Korea, out of our environment. Although Samsung requested multiple times an access to our software and corrupted data, we could not provide them an access in order to protect the privacy and data of our customers.

    Samsung asked us to inform you about this:

    Samsung tried to duplicate the failure with latest script provided to them, but no single failure has been reproduced so far.

    Samsung will do further tests, most likely from week 29 onwards, with much more intensive script provided by Algolia.

    After unsuccessful tries to reproduce the issue with Bash scripts we have decided to help them by creating a small C++ program that simulates the writing style and pattern of our application (no files are open with O_DIRECT). We believe that if the issue is coming from a specific way we are using the standard kernel calls, it might take a couple of days and terabytes of data to be written to the drive. We have been informed by Samsung that no issue of this kind have been reported to them. Our server provider has modified their Ubuntu 14.04 images to disable the fstrim cron in order to avoid this issue. For the last couple of months after not using trim anymore we have not seen the issue again.
