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.
