[ Please CC me I am not subscribed to this ML ]
Hi,
I am here on Debian/testing AMD64 and have e2fsprogs version 1.46.1-1
from Debian/unstable.
Just for the sake of completeness:
Here I use a selfmade Linux v5.12-rc1 (and pre-git as of yesterday).
To check the health of my disk I used badblocks the first time.
( All partitions are ExtFS-formatted on /dev/sdc. )
root@iniza:~/DISK-HEALTH# LC_ALL=C badblocks -v -p 1 -s /dev/sdc -o
badblocks-v-p-1-s_dev-sdc_$(uname -r).txt
Checking blocks 0 to 976762583
Checking for bad blocks (read-only test): done
Pass completed, 0 bad blocks found. (0/0/0 errors)
root@iniza:~/DISK-HEALTH# ll
badblocks-v-p-1-s_dev-sdc_5.11.0-11646.1-amd64-clang13-cfi.txt
-rw-r--r-- 1 root root 0 28. Feb 19:33
badblocks-v-p-1-s_dev-sdc_5.11.0-11646.1-amd64-clang13-cfi.txt
Unfortunately, the output-file is empty.
Do I miss something (order of options for example)?
The whole single-pass badblocks run took approx. 3 hours - last I
looked 50% was 01:26 [hh:mm].
On stdout (and in output-file) - no summary of the total-time.
Is that possible to have:
Pass completed, 0 bad blocks found. (0/0/0 errors) + <total-time_of_run>
Thanks in advance.
Regards,

Nope; the output file is a list of block numbers for which badblocks
found problems.

The output file was designed for use to be fed into mke2fs (via the -l
option) or e2fsck (via the -l or -L options). So we can't change the
format of the output file without breaking those programs.
You will note that the output is in the badblocks standard output:
Pass completed, 0 bad blocks found. (0/0/0 errors)
So there should be no confusion in the mind of the person running the
badblocks program.

OK, I see.
So I misunderstood the -o option.
Use time or linux-perf to see the used total-time.

It was clearly documented in the man page:
-o output_file
Write the list of bad blocks to the specified file.
Without this option, badblocks displays the list on
its standard output. The format of this file is
suitable for use by the -l option in e2fsck(8) or
mke2fs(8).
I will say that for modern disks, the usefulness of badblocks has
decreased significantly over time. That's because for modern-sized
disks, it can often take more than 24 hours to do a full read on the
entire disk surface --- and the factory testing done by HDD
manufacturers is far more comprehensive.
In addition, SMART (see the smartctl package) is a much more reliable
and efficient way of judging disk health.
The badblocks program was written over two decades ago, before the
days of SATA, and even IDE disks, when disk controlls and HDD's were
far more primitive. These days, modern HDD and SSD will do their own
bad block redirection from a built-in bad block sparing pool, and the
usefulness of using badblocks has been significantly decreased.

Thanks for the clarification on badblocks usage and usefulness.
OK, I ran before badblocks:
1. smartctl -a /dev/sdc (shell)
2. gsmartcontrol (GUI)
The results showed me "this disk is healthy".
As you said: Both gave a very quick overview.

Just note that not even the device firmware can't really know whether the
block is good/bad unless it tries to read/write it. In that way I still
find the badblocks useful because it can "force" the device to notice
that there is something wrong and try to fix it (perhaps by remapping
the bad block to spare one). Of course you could use dd for that, but
there are several reasons why badblocks is still more convenient tool to
do that.
That said you should also check the SMART data _after_ you run the
badblocks to see if it encountered any read errors and/or remapped some
blocks.

Thanks Lukas.
With gsmartcontrol I archived two logs.
The diff says:
cd ~/DISK-HEALTH/gsmartcontrol
git diff ST1000LM024_HN-M101MBB_S2U5J9CCB68827_2020-05-28.txt
ST1000LM024_HN-M101MBB_S2U5J9CCB68827_2021-03-05.txt | egrep -i '
read|remap' | grep -i error
- 1 Raw_Read_Error_Rate POSR-K 100 100 051 - 0
+ 1 Raw_Read_Error_Rate POSR-K 100 100 051 - 2
There are no "remap" keywords in the gsmartcontrol log-files.
I have attached both log-files.
( Hope there is no sensitive data included. )

Hi,
yes, sorry I was not sure what the exact term the SMART is using so I
remapping "remapping" in a descriptive sense. Looking at your output the
field you're looking is "Reallocated_Event_Count" which is 0 in both
cases.

Again thank you!
Now, I now know which keywords are relevant and needed to be inspected
in case of a disk-health-check:
# git diff ST1000LM024_HN-M101MBB_S2U5J9CCB68827_2020-05-28.txt
ST1000LM024_HN-M101MBB_S2U5J9CCB68827_2021-03-05.txt | egrep 'Raw

Well, there are various different types of smart tests that you can
request via SMART, although most of them don't do a full surface scan
on the disk --- simply because on large disks, this can take 24 to 36
hours to read every single sector.
Also, an HDD also does do some background reading and re-writing of
some blocks, to remediate against adjacent track interference (ATI)
and far track interference. In addition, although it's not as bad as
with flash, there is actually a slight effect merely *reading* from a
track can cause minor disturbances in the force^H^H^H^H^H^H adjacent
tracks, and of course, writing to a track can definitely cause a minor
weakening of an adjacent track. This is why, when the disk is idle,
an HDD will spend some of its time reading and then rewriting tracks
that might have been sufficiently weakened by ATI and FTI effects it
would be good to refresh those tracks to prevent data loss.
Some times, when it reads a block which is marginal, it will get the
correct checksum when it retries the read, and in some cases the disk
will automatically rewrite the block with the known correct value. In
that case, where it's not a matter of the media going bad, but merely
the magnetic signal recorded on the media getting weaker, it won't be
necessary to remap the block(s).

Note that badblocks does not support more than 16TB disks currently.
Part of this is because ext4 doesn't support more than 16TB in its bad
blocks inode (which has to use indirect mapped blocks), and part of
this is because of the "do you really want to spend 36 hours doing all
of these reads"?
If someone wants to work on making badblocks support 64-bit block
numbers, patches are gratefully accepted, but it's a lot of work, and
I've never thought it was worth my personal time....

P.S. If there are bad blocks, modern disks will automatically remap
them when you first write to a block. And if the block already
contains data, it won't get remapped until you try writing to the
block, in which case you need to decide how to handle the fact that
the previous contents of that block might contain file data or
metadata block data. So doing something much more sophisticated
probably means more work to e2fsck as well in the ideal case. Or just
buy high quality HDD's, and do regular backups, or use RAID, or use a
cluster file system which uses Reed Solomon Codes or other erasure
encodings. :-)
