Public bug reported: After a write intensive operation (like dd if=/dev/zero of=bigfile) an I/O error is issued and the filesystem is mounted read-only. Further read attempts from the storage result in more I/O errors.
The RAID controller is a Dell/LSI SAS2008 FWVersion(06.00.00.00), ChipRevision(0x03), BiosVersion(07.07.00.00) managing just one RAID10 array with four disks. The following kernels have been tried and gave the same problem: * linux-image-4.4.0-36-generic * linux-image-4.7.4-040704-generic * linux-image-4.8.0-040800rc7-generic All disks are clean when inspected with smartctl. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: kernel-bug ** Attachment added: "Relevant dmesg output" https://bugs.launchpad.net/bugs/1625718/+attachment/4744449/+files/xenial_bug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1625718 Title: I/O error after mpt2sas fault_state 0x265d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1625718/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
