Reatime-clock

[Rene B. <re...@we...>]

Hello!


My realtime-clock on my A4000 is brocken and I can`t boot apus anymore. I 
have replaced the battery but it seems that the RTC-chip does not working 
correctly, because A-Dos sometimes says: "bettery backed up clock not 
found". Maybe I have to replace this chip :-(
Apus crashes with kernel access of bad area at the point where the system 
clock is setting up by reading the RTC. Has anyone an idea?
Sometimes I can boot apus, if I manualy set the RTC with "setclock save" 
under A-Dos before booting apus. But then fsck is forced, damn ext2.


Ciao, Renè

Can you boot a kernel with RTC disabled or configured as a module and
remove the module? Or failing that, maybe someone could build such a
kernel for you?

ext3 will be in 2.4.15. :)

This works! Thanks.

What about XFS from SGI? I`m using it on my x86 linux box. It was 
originaly developed and used for SGI-workstations and 
SGI-supercomputers(Cray). I guess its the best filesystem at all.

 I;m using it on APUS machine for over 2 months now and i;m quite happy
with that.. never had any trouble so far (and my machine runs 24/7). I
think it's more mature than ReiserFS and it shouldn't have any hidden bugs
wrt (wrong) endianess. Test i've seen also show that it's one of the best
FS out there (performance wise).

BTW a few days ago i switched my old A1200 to A4000. Thats quite a change!

Do I understand this right, you using XFS on APUS? I can`t find XFS on the 
source tree. Have you just take it from the source tree at 
http://oss.sgi.com and compile it with APUS?

 It's not there as it's not incorporated in any kernel tree (Reiserfs is
included thou). Just take the patch and aply it to kernel source. If You
want i put XFS enabled kernel somewhere on ftp.

Thanks, but its not necessary, I could patch my own kernel. I`m surprised 
that it works with APUS...

I second that. I switched from ReiserFS to XFS on this PowerBook a while
ago (the curious can read up the reasons in the debian-powerpc archives)
and was rewarded by a significant increase in performance. I'm using the
snapshot patches from ftp://oss.sgi.com/projects/xfs/download/patches/.


The reason I mentioned ext3 specifically is that it will be included in
the official kernel soon and that moving from ext2 to ext3 is trivial.

hi,

aye. theres a tool that will convert your mounts , wheres with ext2 -> XFS
or Reiser you have to move all data off, format and then replace data
