failed to ping input output error
EIO on freshly restarted nodeAgile Board ExportXMLWordPrintable Details Type: Bug Status: Open Priority: Major Resolution: Unresolved Affects Version/s: Lustre 2.3.0, Lustre 2.1.1 Fix Version/s: None Labels: None Severity: 3 Rank (Obsolete): 4035 Description I have two nodes, "oss1" and "mds1".
Lctl Ping Input Output ErrorI can lctl ping from oss1 to mds1 with no problem, proving basic lctl ping fails infrastructure is correct. If I kill mds1 (i.e. pull the power cord) and boot it back up and start lnet, failed input output error 5 the first lctl ping from oss1 to it will fail with an EIO. A subsequent lctl ping will succeed. In terms of network traffic when this happens, 3 TCP sessions from oss1 to mds1
Volume Erase Failed Input Output Errorare established, serially - that is 1 is opened and then closed, 2 is opened and then closed and 3 is opened and left open. The first two exchange a few packets each and close down gracefully. The third seems to be much longer lived and is in fact the session where both the failed and then the successful lctl ping happen and it continues to live
Final Close Failed Input Output Erroron. Clearly this problem is not an artefact of TCP or IP and is entirely an artefact of LNET itself, so it seems that LNET ought to be able to handle this situation more gracefully.

In the above scenario, if "mds1" is the MGS, registration of a new OST can fail to reach this freshly rebooted MGS and results in: # mount -t lustre -o loop /var/tmp/test_ost /mnt/lustre/ost3 mount.lustre: mount /dev/loop1 at /mnt/lustre/ost3 failed: Input/output error Is the MGS running?

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 repair this annoying recurrence. Last edited by manish_jain; September 27th, 2008 at 12:48 AM.
