Re: Ext3 - Frequent read-only FS issues



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

I have a bunch of mail servers running postfix (external smtp),

into read-only mode forcing recovery using fsck.

Below are the errors we have seen so far on these systems and those
systems config. The ext3 errors are common in many cases.

Forgot to mention that all ext3 mounts are ordered

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