Hi

There's a crash in the test shell/lvchange-rebuild-raid.sh when running
the lvm testsuite. It can be reproduced by running "make check_local
T=shell/lvchange-rebuild-raid.sh" in a loop.

I have problem to run the cmd (not sure what I missed), it would be better if
the relevant cmds are extracted from the script then I can reproduce it with
those cmds directly.

I didn't read other mails in this thread, only for above issue.
If you use opensuse, systemd service tmp.mount uses nodev option to mount 
tmpfs on /tmp.
From my experience, there are two methods to fix(work around):
1. systemctl disable tmp.mount && systemctl mask tmp.mount && reboot
2. mv /usr/lib/systemd/system/tmp.mount /root/ && reboot

I am using centos similar system, I can try leap later. Appreciate for the 
tips, Heming.

You can always redirect default /tmp dir to some other place/filesystem that 
allows you to create /dev nodes. Eventually for 'brave men'  you can let lvm2 
test suite to play directly with your /dev dir.  Normally nothing bad should 
happen, but we tend to prefer more controled '/dev' managed for a test.

Here are two envvars to play with:


make check_local T=shell/lvchange-rebuild-raid.sh LVM_TEST_DIR=/myhomefsdir  
LVM_TEST_DEVDIR=/dev

LVM_TEST_DIR for setting of dir where test creates all its files

LVM_TEST_DEVDIR  you can explicitly tell to keep using system's /dev   
(instead of dir created within tmpdir)
