Hi All,
I have a kernel log entry I've never seen before:
JBD: barrier-based sync failed on cciss!c0d0p3-8 - disabling barriers JBD: barrier-based sync failed on cciss!c0d0p1-8 - disabling barriers
Should I worry? Can it be blamed for the poor I/O performance? How can I solve this problem? Even if it doesn't mean too much (what I should worry about), it's a bit annoying (as always) to see odd messages.
The ext4 filesystems were created by the installer of an older (ubuntu) distribution, I guess, it can cause problems after the upgrade. Can I convert/modify the filesystem (like with tune2fs) not to have these messages and problem?
Thanks a lot in advance for anyone who has some suggestion.
