PPC Hard reset today

1 Reply

After getting my 8gig microSDHC card for my phone, I decided to do a hard reset and re-install the software back on the device. I am going to treat the 8gig memory as part of the onboard memory, and dump software there. (as well as music, maps….etc)
So with the K’s Rom 1.31, with some software removed (HTC Home) here’s how much ram is available after a soft reset:
Storage: Total 66.80MB, in Use: 6.68MB, Free: 60.12MB
Program: Total 48.77, In Use: 23.48MB, Free 25.29MB
After recovering all the PIM data:
Same.
After installing PointUI 1.02,
Storage: Total 66.80MB, in Use: 10.29MB, Free: 56.51MB
Program: Total 48.77, In Use: 29.50MB, Free 19.27MB
Huge drop in available program memory; 6MB worth…

XEN/server thoughts

Leave a reply

I have crashed the xen dom0 server again. Well not crashed, just that I can’t access the RAID5 data anymore until I reboot.
This has happened before, and is avoidable by not copying any files in dom0 to/from the RAID5 mount point. But today I got carried away, and did just that.

Anyway this has spawned thoughts or a re-organization. I have tried to install XEN 3.2, but it didn’t seem to want to start, so I chalked it up to the fact that the xen-tools-iomem files didn’t have a 3.2 version.

I briefly checked opensuse 11.0, and I think it comes with xen 3.2 (but I”m not 100% sure). So I could upgrade the opensuse 10.3 to 11.0 alpha just to test xen 3.2. I don’t know if 3.2 will fix this issue, so it seems like a pretty long shot just to test for a feature.

The other option is to move the 4 drive RAID array to a FreeNAS or OpenFiler xen virtual machine. This would be much less effort, since all that would really change is where the RAID management software resides. The base xen server software would remain intact.
This option would however require me to buy a 500gig drive to mirror the existing data, make the drive change (in software) and copy the data back, then return the HD.

The other option is to do nothing. Everything works just fine, so I just need to remember to not make this mistake again, and all will be well.

Managing NXserver

Ran into a problem this morning when I couldn’t log into my home server from work.
Too many suspended sessions hanging around would not allow another connection to be made.

Server crashes

Leave a reply

I’ve been having the main server crashing on a consistent basis since it went up. Every week or so seems to be the life of it…
I found nothing in logs… (maybe I didn’t look hard enough?)

So in an effort to see if it may be memory related, I moved the ‘old’ memory stick from one location to another. From slot 1 to 4, or 4 to 1…. dunno which one was which.
It’s not closest to the CPU fan.
The two central slots are running the ‘new’ memory modules.

The ram that’s in there is is PC5400 (667Mhz)
