I’ve recently installed CentOS / RHEL 6.x on the server. I’m getting the following messages in /var/log/messages file logged frequently :
Oct 13 14:00:20 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2
Oct 13 14:05:57 server1 kernel: usb 1-7: reset high speed USB device using ehci_hcd and address 2

I‘ve used the mdadm command line utility to setup and manage software RAID 6 under Debian Linux server. However, I get the following message in /var/log/messages file:

How do I fix the message ‘JBD error message “barrier-based sync failed”‘?
