Zdenek Kabelac	535f7209d2	tests: request 1.12 for reshaping raid ... We will need 1.12 as the kernel needs some mandatory md fixes, otherwise random freezes may appear.	2017-06-23 18:44:01 +02:00
Heinz Mauelshagen	149e4fa04b	test: consider changed default ... commit b81b4aad24 raised the region size so demand the sizes the test checks for.	2017-04-22 00:42:09 +02:00
Heinz Mauelshagen	a004cceed2	test: Adjust previous commit ... Change have_single_core to have_multi_core and go back to || logic in related test scripts.	2017-04-21 01:21:24 +02:00
Heinz Mauelshagen	18bf954801	test: Fix skip some reshape tests that hang on single core machines ... Fix commit c7fb0cb861.	2017-04-20 21:45:56 +02:00
Alasdair G Kergon	c7fb0cb861	test: Skip some reshape tests that hang on single core machines ... Skip hanging raid reshape tests until https://bugzilla.redhat.com/1443999 is fixed	2017-04-20 20:05:07 +01:00
Heinz Mauelshagen	76b843a4bf	test: adjust to proper dm-raid target version ... Adjust to final target version 1.10.1 supporting reshape properly and to recently changed report field specifications (e.g. rehape_len_le) to allow these tests to run. Lower mirror region size to suite the tiny test VG.	2017-03-16 21:17:58 +01:00
Heinz Mauelshagen	48778bc503	lvconvert: add new reporting fields for reshaping ... During an ongoing reshape, the MD kernel runtime reads stripes relative to data_offset and starts storing the reshaped stripes (with new raid layout and/or new stripesize and/or new number of stripes) relative to new_data_offset. This is to avoid writing over any data in place which is non-atomic by nature and thus be recoverable without data loss in the transition. MD uses the term out-of-place reshaping for it. There's 2 other areas we don't have report capability for: - number of data stripes vs. total stripes (e.g. raid6 with 7 stripes toal has 5 data stripes) - number of (rotating) parity/syndrome chunks (e.g. raid6 with 7 stripes toal has 2 parity chunks; one per stripe for P-Syndrome and another one for Q-Syndrome) Thus, add the following reportable keys: - reshape_len (in current units) - reshape_len_le (in logical extents) - data_offset (in sectors) - new_data_offset ( " ) - data_stripes - parity_chunks Enhance lvchange-raid.sh, lvconvert-raid-reshape-linear_to_striped.sh, lvconvert-raid-reshape-striped_to_linear.sh, lvconvert-raid-reshape.sh and lvconvert-raid-takeover.sh to make use of new keys.

Heinz Mauelshagen	76f60cc430	lvconvert: add missed new test scripts for reshaping ... Add aforementioned but forgotten new test scripts lvconvert-raid-reshape-linear_to_striped.sh, lvconvert-raid-reshape-striped_to_linear.sh and lvconvert-raid-reshape.sh Those presume dm-raid target version 1.10.2 provided by a following kernel patch.
