Hi Michael/Jeff, Analysis which we found, 1.Only IO read operation generate errors and No errors was found with IO WRITE that to only on the host side communication. Ubuntu Host with QL4000 NIC < ----- > Switch Ethernet Port : issue is seen. Switch < ----- > Powerstore target : No issue is seen.
2.Issue is observed on Host side communication which is having a problem with 32gig link speed of the Powerstore. No issue is seen with 16gig link. 3. OS logs get flooded with error messages of qedf driver but the data that is read from Target is not corrupted which is read back without corruption. There is no functionality loss. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1950778 Title: Ubuntu 20.04.3 generates IO error message during FIO stress. Status in linux package in Ubuntu: Incomplete Bug description: With fio stress on Powerstore fcoe drives (lun) attached by using Qlogic QL41000 series controller, ubuntu 20.04.3 on MX740c blade server generates below mentioned i/o errors. Nov 11 20:25:17 e2e-l10-058234 kernel: [0000:3b:00.3]:[qedf_process_error_detect:1523]:13: Error detection CQE, xid=0x7bd Nov 11 20:25:17 e2e-l10-058234 kernel: [0000:3b:00.3]:[qedf_process_error_detect:1525]:13: err_warn_bitmap=00000040:00000000 Nov 11 20:25:17 e2e-l10-058234 kernel: [0000:3b:00.3]:[qedf_process_error_detect:1529]:13: tx_buff_off=00000000, rx_buff_off=00000000, rx_id=041b Nov 11 20:25:19 e2e-l10-058234 kernel: [0000:3b:00.2]:[qedf_process_error_detect:1523]:3: Error detection CQE, xid=0x34d Nov 11 20:25:19 e2e-l10-058234 kernel: [0000:3b:00.2]:[qedf_process_error_detect:1525]:3: err_warn_bitmap=00000040:00000000 Nov 11 20:25:19 e2e-l10-058234 kernel: [0000:3b:00.2]:[qedf_process_error_detect:1529]:3: tx_buff_off=00000000, rx_buff_off=00000000, rx_id=01f7 Steps to reproduce. 1. Configure QL41000 series controller on MX MX740c blade server. 2. Configure APM3246 array directly connected to chassis module MX9116n. 3. Install Ubuntu 20.04.3 in any local drive. 4. start I/O by using fio : # fio FileSystemCreateSingle/fio_test.cfg then we can observe error message in syslog To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1950778/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
