Hello,
i was upgrading dom0 to centos 5.3 and the yum update does upgrade the kernel
to 2.6.18-128.1.6.el5xen
the xen version installed is:
xen-3.0.3-80.el5_3.2
xen-libs-3.0.3-80.el5_3.2
kernel-xen-2.6.18-128.1.6.el5
after updating i starting to see this when running 'ps aux' command:
root 15666 0.0 0.0 0 0 ? S< 02:39 0:00
[blkback.17.sda1]
root 15667 0.0 0.0 0 0 ? S< 02:39 0:00
[blkback.17.sda2]
root 16270 0.0 0.0 0 0 ? S< 02:46 0:00
[blkback.18.sda1]
root 16271 0.0 0.0 0 0 ? S< 02:46 0:00
[blkback.18.sda2]
root 16889 0.0 0.0 0 0 ? S< 02:53 0:00
[blkback.19.sda1]
root 16890 0.0 0.0 0 0 ? S< 02:53 0:00
[blkback.19.sda2]
root 17480 0.0 0.0 0 0 ? S< 02:56 0:00
[blkback.20.sda1]
root 17481 0.0 0.0 0 0 ? S< 02:56 0:00
[blkback.20.sda2]google search doesn't help much, some of the search result
said that they have problem with the networking, however all the domU on my
server seems to be working normal. what is blkback anyway? is this normal
processes? if not how to fix it?
thank you
Best Regards,
Markus
