Description

Trying to create a file after setting up changelogs on a fresh new FS yields an IO error:

# lustre/tests/llmount.sh
(...)
# lctl set_param mdd.*.changelog_mask=MTIME
mdd.lustre-MDT0000.changelog_mask=MTIME
# lctl --device lustre-MDT0000 changelog_register
lustre-MDT0000: Registered changelog userid 'cl1'
#touch /mnt/lustre/file
touch: setting times of '/mnt/lustre/file': Input/output error

dmesg provides some interesting information:

# dmesg -H | tail -n 3
