disk replacement on srv137-bud.infra.mirantis.net

[Alexander Gubanov]

Hi devops!

I'd like to replace both disks (details below) on server srv137-bud.infra.mirantis.net
because it fails.

Proof:

root@srv137-bud:~# smartctl -a -d sat /dev/sda | egrep '^(Serial|Device M| 5|196|197|User|# 1])|[1-9]0%'
Device Model: Samsung SSD 850 EVO 500GB
Serial Number: S2RBNXAH116140N
User Capacity: 500,107,862,016 bytes [500 GB]
  5 Reallocated_Sector_Ct 0x0033 099 099 010 Pre-fail Always - 3
# 1 Extended offline Completed: read failure 90% 4941 221437880

root@srv137-bud:~# dd if=/dev/sda of=/dev/null skip=221437880 count=1
dd: error reading ‘/dev/sda’: Input/output error

As we have software raid0 for / partition after disk replacement we need to reinstall OS - Ubuntu 14.04.4 x86_64.
Currently server is removed from jenkins pool and ready for maintenance. I confirm data loss.

I've created the following ticket to replace the disk: https://mirantis.jira.com/browse/IT-31063.

The both disks were replaced on the server. The server was redeployed too. Please check and confirm.
