Hello, I have a new ssd, I encrypted a partition and installed reiserfs (did that on my 15.1 system). Plugging it to my pad with 15.3 I saw that it canot handel it, and searching I found that Opensuse decided to make my backups worthless. So I plugged it again to the 15.1. used fdisk to delete the partition. made a new partition in fdisk. Wet to yast, clicked to istall an encrypted ext4 system. As after the last click the window disappeared without further notice I assumend it was done and unplugged the ssd. Received a nice message, that a process was iterrupted (and I thanked a lot to the highly itelligent programmer who closes a window without any hint about a still running process...). Ok, wanted to repeat. But Yast says it cannot istall ext4 because some cr_xxx is already here. So again fdisk, delete partition, make a new one, back to Yast, same error. So I wet the manual way (the ssd partition is sdg1): dd_rescue -m 2M /dev/urandom /dev/sdg1 cryptsetup -v --key-size 256 luksFormat /dev/sdg1 my_cryptkey-file cryptsetup luksOpen /dev/sdg1 cr_sdg1 mkfs.ext4 /dev/mapper/cr_sdg1 /dev/mapper/cr_sdg1 here I get: mkfs.ext4: invalid blocks '/dev/mapper/cr_sdg1' on device '/dev/mapper/cr_sdg1' Did I do an error? How can I get my ssd back into a virgin state, to begin from scratch? I need urgent help, because I go to travel tomorrow and must take those ssd with me, working on 15.3... Thank you very much for your help. Daniel -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com

here I get: mkfs.ext4: invalid blocks '/dev/mapper/cr_sdg1' on device '/dev/mapper/cr_sdg1'

of course you get an error there, you specified the device TWICE.

Ok, can you then tell me please how the correct syntax would be? I just copied the phrase I use with reiserfs: /sbin/mkfs.reiserfs -j /dev/mapper/cr_sdg1 /dev/mapper/cr_sdg1 This works. I just tried it on that disk, and there is now a working reiserfs, but cannot use that on the pad, so I must change it to ext4.

Just specify only the partition to format: mkfs -t ext4 /dev/mapper/cr_sdg1 Josef -- SUSE Software Solutions Germany GmbH Maxfeldstr. 5 90409 Nürnberg Germany (HRB 36809, AG Nürnberg) Geschäftsführer: Felix Imendörffer

Right. Or: mkfs -L SomeName -t ext4 /dev/mapper/cr_sdg1 -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

Yes. I never do that, always "e2label ..." later, but your command line sounds like A Good Idea ;-) Good luck, and "be careful out there"! Josef -- SUSE Software Solutions Germany GmbH Maxfeldstr. 5 90409 Nürnberg Germany (HRB 36809, AG Nürnberg) Geschäftsführer: Felix Imendörffer

Thank you Josef and Carlos for the fast and efficient help! I used Carlos' version of the command and had full success: it simply worked and the ssd now works on both systems. Uff.

Hi again, here is the start of the large (402 mails) discussion. ================================================================================================= Re: [opensuse-factory] [PLEASE SPEAK UP] Disabling legacy file systems by default? Am 30.01.19 um 17:41 schrieb Martin Wilck:

SUSE will blacklist a number of legacy and/or less frequently used file systems by default on SLES for security reasons.

The proposed list can be seen here:

https://github.com/openSUSE/suse-module-tools/pull/5/commits/8cb42fb6658f210...

The question is now whether we should do the same for openSUSE. I figure that while the above list is probably not controversial for enterprise customers, openSUSE users may have objections to some items on the list. Please speak up if you do.

In any case, note that even if we do this, you can re-enable the filesystems you need by simply commenting out lines in the blacklist file.

sorry, i have no idear how to use the online mailinglistarchiv.

Well providing a link to the archive, or the ID of the message would probably help anybody trying to find that thread, as well as the name of the list.

According to the github link, all that was proposed (and perhaps has now happened?) was to block the kernel from automatically loading a module for some little-used filesystems when a USB disk is inserted, to help prevent attacks. That seems a reasonable thing to do as [presumably] one can simply arrange for the relevant module to be loaded in advance, if one wishes to use one of the affected filesystems. Also, I don't see reiserfs in the list, so I'm not sure of the relevance to Daniel's problem? But without some link to the relevant thread, I've no way to check my suppositions.
