Description

sanity/test_413a failure/timeout example at https://testing.whamcloud.com/test_sets/2398dece-98fe-44d8-b89d-3c76dbef0216

conf-sanity/test_32[b,c,e,h] failures example at https://testing.whamcloud.com/test_sets/431e1d95-39e3-43bb-b721-df2e51d0ea6f

all look directly related to LU-18646 findings ("dd if=/dev/zero ..." commands do not consume expected space due to ZFS recently using data compression by default) and could be fixed the same way (https://review.whamcloud.com/c/fs/lustre-release/+/57871).

there are more conf-sanity subtests failures following but they do not look directly caused by this same problem and may only be consequences of the first failures...
