#81 Cannot write on ext2/ext3 with Leopard
I can easily mount ext2 and ext3-partitions on a MacBook Air using 10.5.2 Leopard. Unfortunatly I can't write on these partitions. I tried checking them with e2fsck, converting the ext3-partition to a ext2-partition, to no avail. It always mounts read-only:
/dev/disk2s3 on /Volumes/Storage (ext2, local, nodev, nosuid, read-only, noowners)
It says in the "info"-part, that it is not writable. But why?

I found a flag that doesn't work with this ext2. It can be disabled from a linux-system with the following command:
sudo tune2fs -O ^dir_index /dev/sdb3
Then you need to re-check the system:
sudo e2fsck -fyD /dev/sdb3
After that it works also under MacOSX...

try to turn off disk indexing...
and be carefull, on mactel, this driver is much less reliable than on ppc mac. at least on tiger 10.4.11 (ppc) vs tiger 10.4.7 (x86)

Yes, I saw that it's unstable on Mactel, I had to reboot 4 times already or so :( Any hint on to where it does that?
Any other ext2-driver for MacOS? ext2fuse perhaps?
OT: But all my tries to install Ubuntu on the machine didn't work so far, as I don't have an external CD-ROM... This must be the reason they didn't ship one with it ;)

I'm having this issue too with 10.5.2...any progress on fixing it? It'd be worth some money to me to get this fixed...

same here. same version. partition is mounted as read only. How to mount it rw?
Logged In: NO
Yes, turning off dir_index will work, but I have seen several kernel panic after using this driver extensively for writing to ext2 partition. It isn't stable on Intel Mac at all.

You should desactivate the index directory and then it will work fine....
It's because dir_index is set to Oui you will have to change dir_index with tune2fs to No to allow write mount.
