| * [PATCH] Avoid console spam with ext3 aborted journal.Stephen Tweedie2005-05-181-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid console spam with ext3 aborted journal. ext3 usually reports error conditions that it detects in its environment. But when its journal gets aborted due to such errors, it can sometimes continue to report that condition forever, spamming the console to such an extent that the initial first cause of the journal abort can be lost. When the journal aborts, we put the filesystem into readonly mode. Most subsequent filesystem operations will get rejected immediately by checks for MS_RDONLY either in the filesystem or in the VFS. But some paths do not have such checks --- for example, if we continue to write to a file handle that was opened before the fs went readonly. (We only check for the ROFS condition when the file is first opened.) In these cases, we can continue to generate log errors similar to EXT3-fs error (device $DEV) in start_transaction: Journal has aborted for each subsequent write. There is really no point in generating these errors after the initial error has been fully reported. Specifically, if we're starting a completely new filesystem operation, and the filesystem is *already* readonly (ie. the ext3 layer has already detected and handled the underlying jbd abort), and we see an EROFS error, then there is simply no point in reporting it again.

| * [PATCH] block_read_full_page() get_block() error handling fixAndrew Morton2005-05-171-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If block_read_full_page() detects an error when running get_block() it will run SetPageError(), then it will zero out the block in pagecache and will mark the buffer_head uptodate. So at the end of readahead we end up with a non-uptodate pagecache page which is marked PageError. But it has uptodate buffers. The pagefault code will run ClearPageError, will launch readpage a second time and block_read_full_page() will notice the uptodate buffers and will mark the page uptodate as well. We end up with an uptodate, !PageError page full of zeros and the error is lost. (It seems a little odd that filemap_nopage() runs ClearPageError(). I guess all of this adds up to meaning that for each attempted access to the page, the pagefault handler will retry the I/O. Which is good and bad. If the app is ignoring SIGBUS for some reason we could get a lot of back-to-back I/O errors.) Fix it by not marking the pagecache buffer_head as uptodate if the attempt to map that buffer to a disk block failed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2 on an ext2 filesystem with 1024 byte block size, on SMP i386 with 4096 byte page size over loopback to an image file on a tmpfs filesystem, I would very quickly hit BUG_ON(!buffer_async_write(bh)); in fs/buffer.c:end_buffer_async_write It seems that more than one request would be submitted for a given bh at a time. What would happen is the following: 2 threads doing __mpage_writepages on the same page. Thread 1 - lock the page first, and enter __block_write_full_page. Thread 1 - (eg.) mark_buffer_async_write on the first 2 buffers. Thread 1 - set page writeback, unlock page. Thread 2 - lock page, wait on page writeback Thread 1 - submit_bh on the first 2 buffers. => both requests complete, none of the page buffers are async_write, end_page_writeback is called. Thread 2 - wakes up. enters __block_write_full_page. Thread 2 - mark_buffer_async_write on (eg.) the last buffer Thread 1 - finds the last buffer has async_write set, submit_bh on that. Thread 2 - submit_bh on the last buffer. => oops. So change __block_write_full_page to explicitly keep track of the last bh we need to issue, so we don't touch anything after issuing the last request.
