Subject: barrier-based sync failed - disabling barriers
Date: Tue, 18 Oct 2011 10:11:59 +0200	[thread overview]
Message-ID: <20111018081159.GA21728@vega.lgb.hu> (raw)

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.

Regards,

Gábor Lénárt
