/hdd3 As Ext2?

[daniel3000]

Hello,

due to file system problems (filesystem panic, FAT error, drive was always remounted read only automatically) I had to reformat my /hdd3 (SL-C3000) and restore a backup. fsck.vfat didn't help anymore.

I unmounted it and did a mkdosfs -F 32 /dev/hda3

Well, now I'm afraid that I'll have file system problems again, and I really don't want to go through this procedure once more.

So I wondered if I can easily instead format it with ext2 or even ext3 without having problems. Anyone knows?

I don't see any point in making this drive vfat. I think this is only important if the drive is read by a Windows machine, which is never the case in the SL-C3000.
Even if the contents are provided by Samba through the network, the file system doesn't matter. Only (maybe?) if the usbstorage PC link setting is used, but I avoid that anyway.

Thanks a lot

Yes you can but you will need to edit the ro.filesys script (I think that's it) to change the mount commands to be ext3 instead of vfat.  If you do that it will work just fine, with the exception that a windows box won't be able to mount it as usual.

hmm - no such script here, at least I couldn't find it.
So you know its location or does anyone know if it's called differently in cacko ROM?

thanks

Did you try a reinstallation of Sharp Rom v1.11JP ?

OR with menu on+OK , option 3 then 1. (reset /hdd3 to factory settings)

No, I backed up all data and did a mkfs.vfat -F32 /dev/hda3.
But I think that is what happens if the hdd3 is set to factory defaults (and some standard directories may be created, but they are in my backup already, so no need to let them create).

I also found the script now, it is called /etc/rc.d/rc.rofilesys, but it contains only the line

Code: [Select]

#exit 0
Is there any other config file / script holding the relevant information or is the filesystem type determinded automatically under Cacko ROM?

found this http://thegrinder.ws/zaurus/conver-t-hdd3-...xt3-filesystem/ , its a nice how-to, it is not mine but I put it up on my site anyways, let me know if it turns out ok.

[bam]

I started looking into this too, I too only found one line of code, how unusual.

[bam]

Some more nfo, everything I have read so far says the first poting I did is correct.

Code: [Select]

$ diff rc.rofilesys.orig rc.rofilesys
84c84
< mkfs.vfat -F 32 /dev/${IDE1}3 2> /dev/null > /dev/null
---
> mke2fs $MKE2FSOPT /dev/${IDE1}3 2> /dev/null > /dev/null
105c105
 < mount -t vfat -o noatime,quiet,umask=000,iocharset=utf8 /dev/${IDE1}3 /hdd3
---
> mount -t $LINUXFMT -o noatime /dev/${IDE1}3 /hdd3
202c202
<       mount -t vfat -o noatime,quiet,umask=000,iocharset=utf8 /dev/${IDE1}3 /hdd3
---
>       mount -t ext3 -o noatime /dev/${IDE1}3 /hdd3
264c264
<       mount -t vfat -o noatime,quiet,umask=000,iocharset=utf8 /dev/${IDE1}3 /hdd3
---
>       mount -t ext3 -o noatime /dev/${IDE1}3 /hdd3
you can see where its forcing the fs to be ext3

seems you have to compile the rc.rofilesys

Code: [Select]

Procedure:
1. /root/etc/rc.d/rc.rofilesys compilation
# mount -o remount and rw /
# cd /root/etc/rc.d
# cp -p rc.rofilesys rc.rofilesys.org
# vi rc.rofilesys
and then make the 4 changes for your hdd.

this one is interesting, it actually does a fsck during boot, no more maintenance menu

I might actually do that.....

[bam]

maybe someone with more experience can explain that one, a fsck would be great during a hard reset.

I get "This post is password-protected"...

Thanks for posting all the details. once I can read the article the puzzle will become complete I hope <g>.

I agree that an fsck during a hard reset would be great. However, maybe not during every hard reset but only after a crash (i.e. if the filesystem is not flagged clean) and after so-and-so many mounts.

unpassword protected it, oops....

[bam]

no-one tried the fsck yet? well I might as well try it....
