There are 2 hard drives (normal, magnetic) in software raid 1 on 3.2.41 kernel.
When I write into them e.g. using dd from /dev/zero to a local file (ext4 on default settings), running 2 dd at once (writing two files) it starves all other programs that try to use the disk. Running ls on any directory on same disk (same fs btw), takes over half minute to execute, same for any other disk touching action. Did anyone seen such problem, where too look, what to test? What could solve it (other then ionice on applications that I expect to use hard drive)? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
