Is there a file system for linux where it's possible (and safe) to perform a file system check while it's mounted read write or which does not need to be checked periodically ?

E.g. a file system whose check first 'grabs' the entire file system and then releases those parts which have been checked already.

(I'm looking for file systems with capabilities like ext2 or better, i.e. something I could use as a replacement for a root or /home file system on a PC)

I'm seeing network problems with a (RHEL) node (packets dropped), which also seem to manifest themselves by a non-zero count of the 'error' and 'frame' fields in ifconfig output:

eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx  
          ...
          RX packets:277593775 errors:1049 dropped:0 overruns:0 frame:536

Is there a detailed description somewhere what the exact meaning of 'errors' and 'frame' is ?

EDIT: output of ethtool eth2:
