`GLIBC_2.28' not found on Synology DSM 7.1.1-42962 Update 3

[MilesTEG1]

Hello, I'm trying to run this tool on my Synology NAS (DS920+, under DSM 7.1.1-42962 Update 3). But I get this error:

root@Syno-DS920Plus:/volume1/homes/Miles/openSeaChest-refs-tags-v22.07-linux-x86_64# ./openSeaChest_FormatUnit --help
./openSeaChest_FormatUnit: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by ./openSeaChest_FormatUnit)

And I don't know how to fix this... There isn't an apt get command on the NAS to update the GLibc version... My version is:

ll -a  /lib64/libc.*
lrwxrwxrwx 1 root root 12 Sep  5 17:52 /lib64/libc.so.6 -> libc-2.26.so

So, is-ti possible somebody made a version compatible with libc-2.26.so ? Thanks in advance. Miles

Hi @MilesTEG1,

Linux binary compatibility is tricky to accomplish, and it's usually due to varying glibc versions between Linux's. So the build you are using came from the Github action using the latest version of Ubuntu with a newer glibc.

This is something that should be solved with the next release we publish as we've received a pull request (#94) that will build packages on CentOS7 which uses an older version. I have also pushed some new cross-compile builds that use musl and cut the dependency problem out entirely.

I've attached the latest build artifact from the musl build and "many linux" build if you would like to try either of them and provide some feedback about whether it worked or not on your NAS. openSeaChest-develop-linux-x86_64-portable.tar.zip Please note that this should be considered an alpha level release at this time since it has not had thorough testing yet.

hello @vonericsen Both versions you provide in the archive file joined with your message works on my Synology ! Thank you very much.

My goal using this tool is to set 4Kn for my new WD Red Plus 4To harddrive directly into the NAS. Because if I had to use my windows computer, I only have an USB3 dock... Your last comment:

Please note that this should be considered an alpha level release at this time since it has not had thorough testing yet. isn't rassuring 😨 Is it relatively safe to use it ?

Thanks again for this version 😃

I'm not sure I can use the tool... The --showSupportedFormats option on the new drive doesn't show 4Kn possibility on it...

Noamly, as the WD doc says:

Advanced Format means 4Kn support, right ?

Hi @MilesTEG1,

While the tool is safe to use, please note that this is an open source tool. We are software/tools developers and write our code based on open standards or anything Seagate Specific we come across that has not been standardized (yet). Devices such as HDD/SSDs are validated & integrated into systems by other teams within Seagate working closely with vendors such as Synology. Our CI process cannot test 100% coverage. So please use this tool based on your comfort level.  

In my experience you are more likely to encounter bugs like the kind that causes a tool to output something strange or to crash unexpectedly.

As for changing drives to 4KN, this tool uses the standardized set sector configuration command to change it, which is an optional feature in newer standards, so it is possible WD does not support it.

Advanced Format typically only means the low-level formatting on the drive is 4K bytes, but the drive may be either 512e (emulated 512 byte access like legacy drives use) or 4KN (matching the physical sector size).

You can see if this feature is listed under Features Supported in the -i output from the drive. Ex: openSeaChest_Format -d /dev/sg? -i

If you do not see the Set Sector Configuration feature listed, then you may need to contact WD to see if there is a way to change the sector size. I do not know if WD has a similar marketing name for this capability (fast format) or if they have some other method to make changes like this.

Hello @vonericsen

If you do not see the Set Sector Configuration feature listed, then you may need to contact WD to see if there is a way to change the sector size. That's it : it doesn't show this feature... Maybe with WD support, but, it may took too long to have an answer... I already replace my fault drive with this one, so I gave up the idea to set 4Kn on this drive. Thanks for your help 😃
