Hi all , I did several loading tests for swift in recent days.
I'm facing an issue ....... Hope you can share you consideration to me ... My environment: Swift-proxy with Tempauth in one server : 4 cores/32G rams Swift-object + Swift-account + Swift-container in storage node * 3 , each for : 8 cores/32G rams 2TB SATA HDD * 7 ===================================================================================== bench.conf : [bench] auth = http://172.168.1.1:8082/auth/v1.0 user = admin:admin key = admin concurrency = 200 object_size = 4048 num_objects = 100000 num_gets = 100000 delete = yes ===================================================================== After 70 rounds ..... PUT operations get lots of failures , but GET still works properly *ERROR log:* Jul 1 04:35:03 proxy-server ERROR with Object server 192.168.100.103:36000/DISK6 re: Trying to get final status of PUT to /v1/AUTH_admin/af5862e653054f7b803d8cf1728412d2_6/24fc2f997bcc4986a86ac5ff992c4370: Timeout (10s) (txn: txd60a2a729bae46be9b667d10063a319f) (client_ip: 172.168.1.2) Jul 1 04:34:32 proxy-server ERROR with Object server 192.168.100.103:36000/DISK2 re: Expect: 100-continue on /AUTH_admin/af5862e653054f7b803d8cf1728412d2_19/35993faa53b849a89f96efd732652e31:Timeout (10s) And kernel starts to report failed message as below *kernel failed log:* 76666 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.020736] w83795 0-002f: Failed to read from register 0x03c, err -6 76667 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.052654] w83795 0-002f: Failed to read from register 0x015, err -6 76668 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.080613] w83795 0-002f: Failed to read from register 0x03c, err -6 76669 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.112583] w83795 0-002f: Failed to read from register 0x016, err -6 76670 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.144517] w83795 0-002f: Failed to read from register 0x03c, err -6 76671 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.176468] w83795 0-002f: Failed to read from register 0x017, err -6 76672 Jul 1 16:37:50 angryman-storage-03 kernel: [350840.208455] w83795 0-002f: Failed to read from register 0x03c, err -6 76673 Jul 1 16:37:51 angryman-storage-03 kernel: [350840.240410] w83795 0-002f: Failed to read from register 0x01b, err -6 76674 Jul 1 16:37:51 angryman-storage-03 kernel: [350840.272Jul 1 17:05:28 angryman-storage-03 kernel: imklog 6.2.0, log source = /proc/kmsg started. PUTs become slower and slower , from 1,200/s to 200/s ... I'm not sure if this is a bug or that's the limitation of XFS. If it's an limit of XFS . How to improve it ? An additional question is XFS seems consume lots of memory , does anyone know about the reason of this behavior?
