HDD Burn-In Test
Burn-In Testskript mit Badblocks
Skript performs these steps:
- Run SMART short test
- Run
badblocks - Run SMART extended test
Schritte:
- Skript (unten kopieren) auf Server (z.B. Proxmox) erstellen:
cd /home/ nano /home/burn-in.sh - Skript als root ausführen mit tmux (https://tmuxcheatsheet.com/), damit Prozesse nach Schließen der Konsole erhalten bleiben
- Pro HDD ein tmux-Fenster
- Test-Run ohne Daten zu schreiben/überschreiben:
sh burn-in.sh -b 4096 /dev/sdb #Blocksize -b 4096 sollte für HDDs bis 16TB reichen, falls Fehlermeldung blocksize auf -b 8192 erhöhen - Full-Test, löscht alle Daten auf HDD!!!!
sh burn-in.sh -b 4096 -f /dev/sdb
- Logfiles werden im selben Ordner erstellt und prüfen
Achtung: Bei FreeBSD Systemen (FreeNAS) folgenden Befehl ausführen, damit badblocks alle Sektoren schreiben darf:

"NAME
$(basename "$0") -- disk burn-in program
SYNOPSIS
$(basename "$0") [-h] [-b <block_size>] [-c <num_blocks>] [-e] [-f] [-o <directory>] [-x] <disk>
DESCRIPTION
A script to simplify the process of burning-in disks. Only intended for use
on disks which do not contain any data, such as new disks or disks which
are being tested or re-purposed.
The script runs in dry-run mode by default, so you can check the sleep
durations and to insure that the sequence of commands suits your needs. In
dry-run mode the script does not actually perform any SMART tests or invoke
the sleep or badblocks programs.
In order to perform tests on drives, you will need to provide the -f option.
OPTIONS
-h Show help text
-e Show extended help text
-b <block_size> Override block size (defaults to 8192)
-c <num_blocks> Override concurrent number of blocks tested
-f Force script to run in destructive mode
ALL DATA ON THE DISK WILL BE LOST!
-o <directory> Write log files to <directory> (default: $(pwd))
-x Run full pass of badblocks instead of exiting on first error
<disk> Disk to burn-in (/dev/ may be omitted)
EXAMPLES
$(basename "$0") sda
run in dry-run mode on disk /dev/sda
$(basename "$0") -f /dev/sdb
run in destructive, non-dry mode on disk /dev/sdb
$(basename "$0") -f -o ~/burn-in-logs sdc
run in destructive, non-dry mode on disk /dev/sdc and
write the log files to ~/burn-in-logs directory
"
readonly USAGE_2=\
"EXIT STATUS
exit 0: script finishes successfully
exit 2: dependencies are missing
not running as 'root'
illegal options are provided
NOTES
Be warned that:
1> The script runs badblocks in destructive mode, which erases any data
on the disk.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!! ALL DATA ON THE DISK WILL BE LOST! BE CAREFUL! !!!!
!!!! DO NOT RUN THIS SCRIPT ON DISKS CONTAINING VALUABLE DATA !!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
2> Run times for large disks can be several days. Use tmux or screen
to test multiple disks in parallel.
3> Must be run as 'root'.
4> The script has the following dependencies:
smartmontools, available at https://www.smartmontools.org
Uses: grep, awk, sed, sleep, badblocks
Performs this test sequence:
1> Run SMART short test
2> Run badblocks
3> Run SMART extended test
The script sleeps after starting each SMART test, using a duration based on
the polling interval reported by the disk, after which the script will poll
the disk to verify the self-test has completed.
Full SMART information is pulled after each SMART test. All output except
for the sleep command is written to both stdout and the log.
You should monitor the burn-in progress and watch for errors, particularly
any errors reported by badblocks, or these SMART errors:
5 Reallocated_Sector_Ct
196 Reallocated_Event_Count
197 Current_Pending_Sector
198 Offline_Uncorrectable
These indicate possible problems with the drive. You therefore may wish to
abort the remaining tests and proceed with an RMA exchange for new drives or
discard old ones. Please note that this list is not exhaustive.
The script extracts the drive model and serial number and forms a log file-
name of the form 'burnin-[model]_[serial number].log'.
badblocks is invoked with a block size of 8192, the -wsv options, and the
-o option to instruct it to write the list of bad blocks found (if any) to
a file named 'burnin-[model]_[serial number].bb'.
Before using the script on FreeBSD systems (including FreeNAS) you must
first execute this sysctl command to alter the kernel's geometry debug
flags. This allows badblocks to write to the entire disk:
sysctl kern.geom.debugflags=0x10
Also note that badblocks may issue the following warning under FreeBSD /
FreeNAS, which can safely be ignored as it has no effect on testing:
set_o_direct: Inappropiate ioctl for device
Tested operating systems:
FreeNAS 9.10.2 (FreeBSD 10.3-STABLE)

VERSIONS
Written by Keith Nash, March 2017
KN, 8 Apr 2017:
Added minimum test durations because some devices don't return accurate
values.
Added code to clean up the log file, removing copyright notices, etc.
No longer echo 'smartctl -t' output to log file as it imparts no useful
information.
Emit test results after tests instead of full 'smartctl -a' output.
Emit full 'smartctl -x' output at the end of all testing.
Minor changes to log output and formatting.
KN, 12 May 2017:
Added code to poll the disk and check for completed self-tests.
As noted above, some disks don't report accurate values for the short
and extended self-test intervals, sometimes by a significant amount.
The original approach using 'fudge' factors wasn't reliable and the
script would finish even though the SMART self-tests had not completed.
The new polling code helps insure that this doesn't happen.
Fixed code to work around annoying differences between sed's behavior
on Linux and FreeBSD.
KN, 8 Jun 2017
Modified parsing of short and extended test durations to accommodate the
values returned by larger drives; we needed to strip out the '(' and ')'
characters surrounding the integer value in order to fetch it reliably.
KN, 19 Aug 2020
Changed DRY_RUN value so that dry runs are no longer the default
setting.
Changed badblocks call to exit immediately on first error.
Set logging directory to current working directory using pwd command.
Reduced default tests so that we run:
1> Short SMART test
2> badblocks
3> Extended SMART test
MS, 9 Sep 2020
Add .editorconfig to streamlime editor behavior for developers.
Remove dependencies on pcregrep and tr.
Add documentation to functions and complex statements.
Reduce code duplication, simplify and decouple code where possible.
Improve portability and resiliency.
Check availability of dependencies during runtim.
Check for root privileges during runtime.
Add option parsing, most notably (-h)elp and -f for non-dry-run mode.
Add dry_run_wrapper() function.
Add disk type detection to skip badblocks for non-mechanical drives.
KN, 5 Oct 2020
Added -x option to control the badblocks -e option, allowing extended testing.
Added smartctl to the list of dependencies.
Changed disk type detection so that we assume all drives are mechanical drives
unless they explicitly return 'Solid State Drive' for Rotational Rate.
Removed datestamp from every line of log output, only emitting it in log headers.
Minor reformatting.
KY, 30 May 2022
Added -b & -c options to control respective badblocks options."
