ext3 partition being reported as ramfs?

Hi,
I'm loving arch so far, but have run into a few issues that I'm confused about.

The strangest is that all of my ext3 partitions are being reported as ramfs by stat.  Everything seems to be working fine, except that I have files that chown doesn't seem to work on (unrelated?).  Any insight would be appreciated.

Chown issue:
As root, I chown -R a particular directory.  If I look through the directory as root, everything looks fine (listed as owned by a non-root user).  If I look at that directory logged in as that user, I get a lot of cannot access/permission denied errors, and ?????? where the permissions should be listed.

Ramfs/Ext3 issue:

No idea about your permission issues. Logs?
I also get "ramfs" with stat. But seriously, stat? Use blkid.

Re: ext3 partition being reported as ramfs?

i can confirm on my system as well.  partitions that are ext3 are reported as ramfs through the the "stat" command only.  mount, df, dmesg, gparted, etc all say ext3.

nothing i could find in "man stat" made me think that it should show anything other than filesystem type with the '-f -c %T' options.

i'd be curious what's going on.

Re: ext3 partition being reported as ramfs?

Thanks for the responses.

Which brings me to:  shouldn't stat be as trustworthy as blkid?  stat is more portable, and more likely to be installed on different systems.  I'm not arguing, I'm just wondering why the info provided by blkid is better.  Because it's part of e2fsprogs and more 'tuned' to ext?
