[Bug 2042363] Comment bridged from LTC Bugzilla
--- Comment From david_pa...@uk.ibm.com 2024-04-24 02:47 EDT--- Hi, We have had a reply from the AIX support team (see below) explaining the RENEW requests. Do you have any further questions for the AIX support team or can we supply any further diagnostic information to progress this issue ? Regarding the comment/question about RENEW reqs from Linux: RENEW is done when half the lease period has elapsed without any state operation going on. Here, the Linux server's lease is 90 seconds. From an NFS perspective, there is nothing strange or remarkable about the pattern of RENEW reqs sent in the good & bad cases. If there is a specific question about renews in the latest captures let us know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2042363 Title: AIX 7.3 NFS client frequently returns an EIO error to an application when reading or writing to a file that has been locked with fcntl() on a Ubuntu 20.04 NFSV4 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From david_pa...@uk.ibm.com 2024-04-18 11:00 EDT--- Hi, Thanks for looking at the logs. I agree that both syslogs (AIX 7.2 and 7.3) contain multiple "TCP recvfrom got EAGAIN" entries. To clarify the information in the attachments, I have updated the comment for the attachments of the syslog for the non-working AIX 7.3 pair (amaliada and adamsongrunter. The syslog is in two parts because the Bugzilla file uploader couldn't handle such a large file. It is NOT mixed with the AIX 7.2 syslog. The syslog for the working pair AIX 7.2 (adia and amberjack) was smaller, so it is a single file attachment. I will ask the IBM AIX support team about the NFS Client lease renewal in both AIX 7.2 and 7.3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2042363 Title: AIX 7.3 NFS client frequently returns an EIO error to an application when reading or writing to a file that has been locked with fcntl() on a Ubuntu 20.04 NFSV4 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From david_pa...@uk.ibm.com 2024-04-17 05:37 EDT--- Hi, I have run the same MQ HA test on a working(AIX 7.2) and non working(AIX 7.3) pair of machines with the same Linux NVSv4 Ubuntu 20.04 (kernel updated to 5.4.0-176-generic). I used the same RPC debug trace options as previously. Here are the details of the uploaded tar.gz file called CASE_TS012306761.tar.gz. I do have other trace files if you need them. AIX 7.3 test was between machine amaliada and partner adamsongrunter on 16/04/2024 starting at 14:01 and failing at 14:04:07:971116 with a failure to write a file on the shared NFSv4 server. There is a partial syslog from the Linux NVSv4 server duckseason covering that period called TS012306761/syslog_16042024_amaliada_primary_adamsongrunter_partner_both_aix73.log Covering the same period, there are a set of tcpdump files in subfolder TS012306761/tcpdumps_amaliada_primary_admasongrunter_partner_both_aix73/ AIX 7.2 test was between primary machine adia and partner amberjack on 17/04/2024 starting at 09:09:48 and ending successfully at 09:16:29. There is a partial syslog from the linux NVSv4 server duckseason covering that period called TS012306761/syslog_17042024_adia_primary_amberjack_partner_both_aix72.log Covering the same period, there are a set of tcpdump files in subfolder TS012306761/tcpdumps_adia_primary_amberjack_partner_both_aix72/ We are happy to supply further info to help resolve this issue.
