OSTs fails after format with error -110? Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] OK, I did a little lctl ping input output error more research and I found that I could increase the verbosity of lctl ping fails the LNET debugging output by doing the following: echo +neterror > /proc/sys/lnet/printk So, I did that and tried one failed input output error 5 of the failing "lctl ping" commands again: [root at lustre-mgs ~]# lctl ping 192.168.1.101 at tcp0 failed to ping 192.168.1.101 at tcp: Input/output error [root at lustre-mgs ~]# Here's what
Volume Erase Failed Input Output Error
I see now in dmesg: [174224.584669] LNet: 3900:0:(lib-socket.c:626:lnet_sock_connect()) Error -113 connecting 0.0.0.0/1023 -> 192.168.1.101/988 [174224.584692] LNet: 3900:0:(acceptor.c:114:lnet_connect_console_error()) Connection to 192.168.1.101 at tcp at host 192.168.1.101 was unreachable: the network or that node may be down, or Lustre may be misconfigured.

Network configuration on each of these machines is very simple; only one interface on any of them is up and running; one port on an Intel X520 10 Gig NIC; I have LNET configured in /etc/modprobe.d/lustre.conf on i.e. the MGS as so: options lnet networks=tcp0(p1p2) That's correct, yes? In this case, p1p1 and p1p2 are the two 10 Gig NIC ports ... I don't know why RHEL uses such funky names ... But very basic, no routing, not even multiple interfaces ... Continuing to research ... I assume error -113 in this case is just a generic "connection failure" type error although if something could be deduced from that, it would certainly be great :O Thanks, Sean On Thu, Jul 2, 2015 at 4:47 PM, Sean Caron

it worked. I think probably it makes sense to add a note about this subnet config in

The kernel version is 2.6.24-19-generic. Sometimes, suddenly something happens and then every command from bash gives the same error: ~$ autoconf -V -bash: /usr/bin/autoconf: Input/output error ~$ ad -bash: /usr/bin/python: Input/output error The file system becomes read-only and no files can even be 'touch'ed. However, uname -r (and possibly other commands) still keep working. If you press Tab-Tab at the terminal, it hangs and then there is no way other than hard-boot to get stuff to work again. Can anyone suggest something to repai

I have the following in / etc/modprobe.conf: options lnet networks="tcp0(eth2)" to specify the third NIC only. I have two OSSs and one MDS. They startup and see each fine. My XML is pasted below. When I try to have a client start with: # lconf --node client lustre-fs.xml it hangs at: + mount -t lustre_lite -o osc=lov1,mdc=MDC_compute-0-1.local_mds1_MNT_client lustre-fs /mnt/ lustre If I check its NIDs, I see: # cat /proc/sys/lnet/nis nid refs peer max tx min [EMAIL PROTECTED] 2 0 0 0 0 [EMAIL PROTECTED] 2 8 256 256 255 which is the correct address for this client. If instead of using lconf, I simply modprobe lnet and run lctl, then I try to ping the MDS. It fails: # lctl lctl > network up LNET configured lctl > network tcp lctl > ping 192.168.1.250 failed to ping [EMAIL PROTECTED]: Input/output error Yet, I can ping the node on the command line: # ping -s 9000 192.168.1.250 PING 192.168.1.250 (192.168.1.250) 9000(9028) bytes of data. 9008 bytes from 192.168.1.250: icmp_seq=0 ttl=64 time=0.142 ms # ping -s 9000 nas-0-0-m PING nas-0-0-m.local (192.168.1.250) 9000(9028) bytes of data. 9008 bytes from nas-0-0-m.local (192.168.1.250): icmp_seq=0 ttl=64 time=0.111 ms If I try using lctl on the MDS to ping the client, it fails as well but I can ping the two OSSs. Any suggestions? Thanks, Scott
