Hi
The commit e879a0d9cb086c8e52ce6c04e5bfa63825a6213c breaks the test
shell/lvcreate-large-raid.sh in the lvm2 testsuite.
The breakage is caused by removing the line "read_bio->bi_opf = op |
do_sync;"
Do I need some special setup to run this test? I got following
result in my VM, and I don't understand why it failed.
Ask Zdenek Kabelac - he is expert in the testsuite.

Hi
Lvm2 test suite is creating 'virtual' disk setup - it usually tries first
build something with 'brd' - if this device is 'in-use' it fallback to
create some files in LVM_TEST_DIR.
This dir however must allow creation of device - by default nowdays /dev/shm
& /tmp are mounted with 'nodev' mount option.
So a dir which does allow dev creation must be passed to the test - so
either remount dir without 'nodev' or set LVM_TEST_DIR to the filesystem
which allows creation of devices.
Yes, I know that, and I set LVM_TEST_DIR to a new mounted nvme, as use
can see in the attached log:
[ 0:02.335] ## DF_H: /dev/nvme0n1 98G 64K 93G 1% /mnt/test
Hi
Please check the output of 'mount' command whether your mount point /mnt/test
allows creation of devices (i.e. does not use 'nodev' as setting for this
mountpoint)
In 'lvm2/test' run 'make help' to see all possible settings - useful one
could be LVM_TEST_AUX_TRACE to expose shell traces from test internals -
helps with debugging...
The log do have shell trace, I think, it stoped here, I just don't know
why :(
[ 0:01.709] ## - /root/lvm2/test/shell/lvcreate-large-raid.sh:31
[ 0:01.710] ## 1 STACKTRACE() called from /root/lvm2/test/shell/lvcreate-
large-raid.sh:31
Run:
'make check_local T=lvcreate-large-raid LVM_TEST_AUX_TRACE=1 VERBOSE=1'
for more closer look why it is failing when preparing devices.
My best guess is the use of 'nodev' flag (thus mount with '-o dev')
