Ext3 - Frequent read-only FS issues

[Steven Chervets]

Dushyanth,

If you have the disk write-cache enabled it means that any power  
outage can cause file system corruption.  I would suggest that you put  
a battery in your disk controller and enable the write-cache on it,  
and at the same time, disable the write-cache on the disk itself.

If you can't get your hands on a battery, then disabled the write- 
cache on the hard disk and see if you get any more file system  
corruption errors.

Good Luck,
Steve

Forgot to mention that all ext3 mounts are ordered

/dev/sdX1 on /mountpoint type ext3  
(rw,noatime,usrquota,grpquota,data=ordered)
