disk replacement on srv131-bud.infra.mirantis.net

[Alexander Gubanov]

Hi devops!

I'd like to replace disks (details below) on server srv131-bud.infra.mirantis.net because it fails.

Proof:

root@srv131-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: S2RBNXAH116165P
User Capacity: 500,107,862,016 bytes [500 GB]
  5 Reallocated_Sector_Ct 0x0033 099 099 010 Pre-fail Always - 1
# 1 Extended offline Completed: read failure 90% 4962 502464946

root@srv131-bud:~# dd if=/dev/sda of=/dev/null skip=502464946 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.

All the disks were replaced and OS was reinstalled on the server. Please check and confirm.
