Title:
ubuntu_blktrace_smoke_test failed with "invalid path" on ARM64 Zesty
Status in linux package in Ubuntu:
In Progress
Bug description:
It looks like the sed in the get_dev() function is the cause.
mount=$(stat -c '%m' $1 | tail -1)
DEV=$(df $mount | grep dev | head -1 | cut -d' ' -f1 | sed 's/[0-9]//g')
Note that this issue does not affect other amd64 systems, the sed
command is for SATA devices there, to change /dev/sda1 to /dev/sda
On ARM64 nodes, the actual DEV should be:
/dev/disk/by-uuid/ec71a3bf-d777-4edb-a0ea-5b6d3504748d
But after the sed command, it will become:
/dev/disk/by-uuid/ecabf-d-edb-aea-bdd
This is what I can see from /dev/disk/by-uuid:
root@ms10-34-mcdivittB0-kernel:/dev/disk/by-uuid# ls
