ECS 2.0 installation issue

Jump to solution

Hi,

After I ran command "./step1_ecs_singlenode_install.py --disk mapper/mpatha", it would prompt:

[09/Jul/2015 04:29:53] INFO [root:247] Partitioning the disk '/dev/mapper/mpatha'

Device does not contain a recognized partition table

Building a new DOS disklabel with disk identifier 0xd75fa9f7.

[09/Jul/2015 04:29:53] ERROR [root:268] Command '['fdisk', '/dev/mapper/mpatha']' returned non-zero exit status 1

Traceback (most recent call last):

    output = subprocess.check_output(["fdisk", disk_path], stdin=ps.stdout)

    raise CalledProcessError(retcode, cmd, output=output)

[09/Jul/2015 04:29:53] CRITICAL [root:269] Aborting program! Please review log.

This error is at line 248:             ps = subprocess.Popen(["echo", "-e", "\"o\nn\np\n1\n\n\nw\""], stdout=subprocess.PIPE)

I manually tried:

[root@xbuiiopubup0028 ecs-single-node]# fdisk /dev/mapper/mpatha

.....snipped.......

Command (m for help): w

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 22: Invalid argument.

The kernel still uses the old table. The new table will be used at

the next reboot or after you run partprobe(8) or kpartx(8)

Syncing disks.

[root@xbuiiopubup0028 ecs-single-node]# echo $?

1

[root@xbuiiopubup0028 ecs-single-node]#

The warning after "w" command in fdisk is normal in Linux...

As a workaround, I had to manually fdisk my disk to create partition, and then replace "w" with "q" in line 248 to bypass, and then rerun the step1*.py.

Hello Leonli,

Thank you for the information. The pre-requirement for the script  physical raw data drive, We did not test the script with multipath devices yet. We would consider to solution for multipath devices in future.
