Zdenek Kabelac	b2431d105e	tests: catch all output ... Previous fix was invalid (after some in-place shuffling) 'dd' copied goes to 'stderr' so we need to catch all output. Grep needs to check output of tee tool. Ensure 'C' locales are in use with 'dd'.	2023-07-17 16:34:14 +02:00
Zdenek Kabelac	f71d3cce93	tests: ensure single leg is broken ... Make sure only the first raid5 leg, that contains searched string is being modified, so we do not 'damage' 2legs at once.	2023-07-15 11:05:35 +02:00
Zdenek Kabelac	04860b6324	tests: correct checked devices ... Fix the testing logic. With raid5 device the layout of files on a filesystem does not define which leg will actually contain the block we try to damage. So test will now figure out which device has damaged block. Use 'check' functionality and also drop unneeded random write as we now can identify easily in other way.	2023-06-25 13:02:36 +02:00
Zdenek Kabelac	4a003ba671	tests: fix pattern for raid4 ... Since the strip in raid4 might be XOR - we might eventually end with 2 blocks of 'B' on 2 disks - so will rest of stripe with 'b'.	2023-04-25 00:12:31 +02:00
Zdenek Kabelac	80ebec099d	aux: add wait_recalc ... Share function across tests.	2023-04-21 14:52:43 +02:00
Zdenek Kabelac	4e0aab7428	tests: convert to use ext4 ... Convert test to use only ext4 instead of 300M demanding XFS. Shorten 'B' files to 4K and use 4K strip size with >raid1 arrays so we do not risk spreading of the file across stripe. Also use easier 'aux corrupt_dev()' method to introduce a bit corruption into a block device with integrity. TODO: shorten _wait_recalc (should't be needed).	2023-04-21 14:52:43 +02:00
Zdenek Kabelac	b2360437e0	tests: use aux clear_dev ... Use wrapper over 'blkdiscard -z'	2023-04-21 14:52:43 +02:00
Zdenek Kabelac	94c4af232c	tests: prohibit 4K brd device with integrity ... Older kernels hit these errors: device-mapper: integrity: Bio not aligned on 8 sectors: 0x8ffc, 0x4	2021-03-20 10:52:24 +01:00
David Teigland	1cc75317f9	tests: integrity mismatch checks for all raid levels ... Verify that corruption is corrected for raid levels other than raid1. For other raid levels, attempt to corrupt the given file pattern on each underlying device, since we don't know which device contains the file being corrupted. This ensures that corruption is actually be introduced when testing the other raid levels. Verify that corruption is being corrected by checking the integritymismatches count is non-zero for the raid LV, which includes the total from all images (since we don't know which image will have the corruption.)	2020-11-11 15:13:46 -06:00
David Teigland	2317ba3934	tests: update integrity tests ... simplified the method of corrupting data, the old method was not working reliably. moved syncation tests to a different file	2020-11-10 17:41:04 -06:00
