'ganesha_mgr display_export - client not listed
by Billich Heinrich Rainer (ID SD) 02 Nov '20

02 Nov '20

Hello, Some nfsv4 client of ganesha does not show up in the output of 'ganesha_mgr display_export'. The client has an active mount, but also shows some nfs issues, some commands did hang, the process just stays in state D (uninterruptible sleep) according to 'ps', but not the whole mount. I just wonder if the client's IP should always show up in the output of display_export once the client did issue a mount call and if the absence indicates that something is broken. Gutr,gut, Putting it the other way round: When is a client listed in the output of display_export and when is it removed from the list? We do collect more debug data, this is just something that catched my eye. Thank you, Heiner We run ganesha 2.7.5-ibm058.05 on a spectrum scale system on RedHat 7.7. I crosspost to the gpfsug mailing list. -- ======================= Heinrich Billich ETH Zürich Informatikdienste Tel.: +41 44 632 72 56 heinrich.billich(a)id.ethz.ch ======================== # ganesha_mgr display_export 37 Display export with id 37 export 37: path = /xxxx/yyy, pseudo = /xxx/yyy , tag = /xxx/yyy Client type, CIDR version, CIDR address, CIDR mask, CIDR proto, Anonymous UID, Anonymous GID, Attribute timeout, Options, Set a.b.c.198/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 a.b.c.143/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 a.b.c.236/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 a.b.c.34/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 a.b.c.70/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 a.b.c.71/32, 0, 0, 255, 1, 4294967294, 4294967294, 0, 1126195680, 1081209831 *, 0, 0, 0, 0, 4294967294, 4294967294, 0, 1126187490, 1081209831

Re: [EXTERNAL] Proxy FSAL client session renewal failures

Problem re-occurred. I restarted Ganesha, and the client mounts were setup, and about 24 hours later, the same failures started happening. I guess I’ll turn up logging to try to see what’s going on. Suggestions welcome… Thanks. -Jeff From: "Becker, Jeffrey C. (ARC-TN)[InuTeq, LLC] via Support" <support(a)lists.nfs-ganesha.org> Reply-To: "Becker, Jeffrey C.

I’m testing Ganesha 3.3 serving about 20 exported filesystems using Proxy FSAL. I set up my config, and started the server. We were able to mount all directories successfully on a pair of clients, and run miscellaneous tests. Everything looked good. However, about 3 hours after a successful server start, I started seeing the following repeatedly in the log. I checked that the NFS server exports were still fine, and we couldn’t find anything significant on either client, so I’m wondering where these are coming from. Is there some timeout? Seeking advice… Thanks. -Jeff 21/09/2020 18:28:43 : epoch 5f68f0da : linux : ganesha.nfsd-48[main] nfs_start :NFS STARTUP :EVENT :------------------------------------------------- 21/09/2020 18:28:43 : epoch 5f68f0da : linux : ganesha.nfsd-48[main] nfs_start :NFS STARTUP :EVENT : NFS SERVER INITIALIZED 21/09/2020 18:28:43 : epoch 5f68f0da : linux : ganesha.nfsd-48[main] nfs_start :NFS STARTUP :EVENT :------------------------------------------------- 21/09/2020 18:30:13 : epoch 5f68f0da : linux : ganesha.nfsd-48[reaper] nfs_lift_grace_locked :STATE :EVENT :NFS Server Now NOT IN GRACE 21/09/2020 21:18:17 : epoch 5f68f0da : linux : ganesha.nfsd-48[pxy_clientid_renewer] pxy_clientid_renewer :FSAL :EVENT :Failed to renew session 21/09/2020 21:18:17 : epoch 5f68f0da : linux : ganesha.nfsd-48[pxy_clientid_renewer] pxy_clientid_renewer :FSAL :EVENT :Failed to renew session 21/09/2020 21:18:17 : epoch 5f68f0da : linux : ganesha.nfsd-48[pxy_clientid_renewer] pxy_clientid_renewer :FSAL :EVENT :Failed to renew session
