Niltze [привет], Artur-

Your issue seems to be that you are mixing incompatible software framework release number (SFRN) formats.

The stable SFRN 4.0.2 format cannot be combined with SFRN 5.1.3. That is probably the reason you are experiencing those errors during mount op.

Thus far the reiser4 -enhanced kernels and utilites that I build are for the stable SFRN 4.0.2 format:

Try those patches pointed by links above, which all are SFRN 4.0.2 format, and you should be able to format, mount, and run on reiser4.

Good luck!

Hello. Thank you, you have done a great job.
I was exciting Reiser4 opportunities on my old laptop with outdated hardware. It seemed like a 2.6 kernel.
I compiled a kernel 5.6.15 with Reiser4 on the board a few days ago. And there was an mounting issue.

There are some errors from journalctl:
[root@user-pc user]# journalctl -xb
reiser4[mount(1298)]: plugin_by_unsafe_id (fs/reiser4/plugin/plugin.c:254)[nikita-2913]:
WARNING: Invalid plugin id: [9:1]

kernel: reiser4[mount(1301)]: reiser4_init_read_super (fs/reiser4/init_super.c:639)[nikita-26091]:

I can ‘mkfs.reiser4‘ but I can’t mount it.

I am also on AMD.

Should I use version GCC-8 instead GCC-10? And what is Reiser4 patch for Debian? Is this the same as official edward6 reiser4 patch?

There is my PKGBUILD
An original PKGBUILD here
There is Kernel config
Could you help me with the issue please?

On my installation of Metztli, I found using the deadline scheduler and turning off all swap really sped things up with no stability issues.

In terminal as root:

1 echo deadline > /sys/block/sda/queue/scheduler

2 swapoff -a

It would be nice if you could give some pronunciation hints for any words in this Linux in Nahuatl, the Aztec language.

Having used it, I think Reiser4 will be an important and uniquely useful Linux file system. Thank you for your contribution and congrats.

Niltze, Per!

I am quite busy at the moment and I don’t know when I will slow down. Sorry.

However, in a chance I will give a try to your Drupal 7.38 (or higher version) under OS/2 and I will let you know how it performs –and if there are issues that could be worked around.

Thank you for the time you took to leave a message.

This is a great “How to"! I now have php5.4 and mySQL5.1 up and running. Since there are new versions of Drupal available since this “how to” was written I thought I should try with drupal-7.38. However, when opening the “install.php I get the following: “system requirements page for more information.’; exit; } // Start the installer. require_once DRUPAL_ROOT . ‘/includes/’; install_drupal();” Any idea how to proceed with this? Or should I try an older version of drupal?

Hola, what’s up?

I really like this blog/page, y es un orgullo ver mexicanos trabajando en este tipo de sector como el IT. I’m not really savvy on IT stuff (yet I know its really important!!), but I think your implementation of the Nepohualtzintzin as “digitized” is very cool. As far as IT in Mexico, sabias usted que Mexico ya se han implementado supercomputadoras de alta rendimiento? El ATOCATL de la UNAM. El AITZALOA de la UAM. El KAN BALAM tambien de la UNAM. El sofisticado XIUHCOATL de la CINVESTAV. Y tambien el numero 1 de toda latino America, el MIZTLI (UNAM) :) Yo me pertenesco, en mi linea de trabajo, a pasar informacion sobre la ciencia y tecnologia a otros/otras que trabajan en estos tipos de area.

Would love to hear what you think, you have my email and I hope you can share your thoughts and/or send me your email so I can put you on my “email newsletter".

1) First, are you using the operating system OS/2?

2) “Will,when I downloaded always prompt ‘no directory specified’,”
.–>When you download what? And from where?

I need to know more info to be able to help you.

Thank you for your comment.
