Hello, According to http://en.wikipedia.org/wiki/Ext3 : If barrier=1 is not enabled as a mount option (in /etc/fstab), and if the hardware is doing out-of-order write caching, one runs the risk of severe filesystem corruption during a crash.
Somewhat scary(?) I suppose that the default value for RHEL ext3 file systems is barrier=0? In systems with RAID/SAN: Is this a problem if the RAID controller has battery backed cache? In systems plain disks: Is this a problem if "hdparm -W 0 <device>" has been run for the disks at boot time? -- Regards, Troels Arvin <[EMAIL PROTECTED]> http://troels.arvin.dk/ _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
