Offhand, no. They're pretty up front about it. I'm not entirely sure of the
shortcomings.

AIX lv is actually very similar to lvm under Linux. Outside of that, yeah,
I've never really had AIX filesystem problems either.

VxFS has some other bits that are somewhat useful, particularly in a
shared-storage SAN type of environment. How I could have used Solaris UFS
logging back in the 2.5 days where a system crash or power hiccup was *sure*
to take out your /etc/passwd file in the process.
DiskSuite is really akin to Linux' md software RAID - you can put the metadata
replicas wherever you want fairly easily however.
I really can't wait until Linux post 2.5.x works back in EVMS support - there
are some very slick things going on there. If you get a chance, play around
with EVMS a bit, it's a really nice suprise.
