Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/a298010c-f721-11e8-86c0-52540065bddc

The test_810 added for LU-11663 fails on ARM on ldiskfs with the following test error:

osc.lustre-OST0006-osc-ffff800039d7f800.checksum_type=adler
fail_loc=0x411
dd: error writing '/mnt/lustre/f810.sanity': Input/output error

The client console logs show the checksums do not match between the client and server so there is still some kind of alignment problem:
