N66u - Warnings and errors in system log

[PeterPasm]

!UPDATE in post #4

Hi,


First of all, I wish a HAPPY NEW YEAR to all =)

I have a couple of strange entries in the syslog,

• Looks like my ext2 partition on the sub disk is mounted as ext4. Why is that happening?, is it a problem?, (and if yes,) how to solve it? (I already ran e2fsck, and checked with a PC too, no problems found)
  
• Transmission fails to set buffers , is that something I should worry about?
  
• what is that time disparity issue at the end?

Thank you.

The error about ext4 on an ext2 partition is most likely due to automounting trying to detect the file system on the disk. My guess is that the driver for ext4 is not the same as for ext2/3, so the router must first try the driver for ext4 before trying the one for ext2/3. If doing the other way around I guess an ext4 drive would be mounted as ext2 thus missing all ext4 features.


The buffer size is probably dues to RAM limitations, not sure if it can be configured (I haven't looked, but it probably can).


The time thing is because the router does not have a real time clock it always boots January 1 1970. Then the clock is set from the internet using ntp, which makes it "skip".

Thanks for the reply!

I understand and this was my assumption as well, I just curious why is it mounted as ext4 at the end by the "ext4 driver" when it's ext2 only?

Thanks I will look into that!


edit: I found this about the transmission warning if anybody is interested.

Just wanted to copy something (on wire) from the HDD to my PC and the speed was terribly slow (3Mbyte/sec). Uploading works fine 14.6Mbyte/sec. NTFS worked great both ways.
The reason I decided to make this entware/ext "move" was to have an irc bouncer running on the router while I sleep, but all the troubles I encountering since really saddens me:/

Any suggestion or help would be greatly appreciated.

I see the same ext4 message in my log, but running the command "mount" shows that my USB volume is correctly mounted as ext3. My wired transfers to that disk top out at around 9 Mb/sec. I get the crond notice as well, and I believe that is due to the Broadcom soc lacking a battery-backed clock.

Yes, but 3Mbyte/sec copy speed from the router is really not acceptable, something is wrong perhaps.

Right, I'm seeing 9-10 MB/s copying from the usb hd attached to my n66u.

Whenever I see a filesystem warning in the log, I unmount the hd from the router, connect it to my pc, and run gparted.

I did everything I could, converted to ext3 and back to ext2, reformated to ext2, and also reformated to ext3 as well, checked in PC, tried different drive too, etc. No matter what I do, only NTFS gives me good speeds. Using any kind of Linux filesystem results in abysmal transfer speeds when copying from the router (copying to the router is "fine", 14.x MB/s with ext2 and 11MB/s with ext3 (NTFS is still a lot faster both ways tho).

I really don't know what else I could try
