NFS Stale File Handle Again, But this happens when mount operation not during accessing file or directory.
My /etc/exports file: /mnt/storage_pool/testnfs00 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs01 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs02 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs03 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs04 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs05 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs06 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs07 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs08 *(rw,sync,no_root_squash) /mnt/storage_pool/testnfs09 *(rw,sync,no_root_squash) Proc info as follows: root@Dahua_Storage:~# cat /proc/net/rpc/nfsd rc 0 5428 3350 fh 600 0 0 0 0 io 0 1195819008 th 8 0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 ra 32 0 0 0 0 0 0 0 0 0 0 0 net 8779 1 8771 1 rpc 8778 0 0 0 0 proc2 18 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 proc3 22 1 819 0 840 1432 0 0 4587 12 0 0 0 829 0 0 0 0 37 10 0 0 210 proc4 2 0 0 proc4ops 59 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 root@Dahua_Storage:~# cat /proc/net/rpc/nfsd.export/content #path domain(flags) /mnt/storage_pool/testnfs02 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd02:00000000:00000000:00000000) /mnt/storage_pool/testnfs04 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd04:00000000:00000000:00000000)/mnt/storage_pool/testnfs00 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd00:00000000:00000000:00000000) /mnt/storage_pool/testnfs05 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd05:00000000:00000000:00000000) /mnt/storage_pool/testnfs01 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd01:00000000:00000000:00000000) /mnt/storage_pool/testnfs03 *(rw,no_root_squash,sync,wdelay,no_subtree_check,uuid=0000fd03:00000000:00000000:00000000) root@Dahua_Storage:~# cat /proc/net/rpc/nfsd.fh/ channel content flush root@Dahua_Storage:~# cat /proc/net/rpc/nfsd.fh/content #domain fsidtype fsid [path] * 6 0x00fd0000000000000000000000000000 /mnt/storage_poo! l/ testnfs00 * 6 0x03fd0000000000000000000000000000 /mnt/storage_pool/testnfs03 * 6 0x02fd0000000000000000000000000000 /mnt/storage_pool/testnfs02 * 6 0x01fd0000000000000000000000000000 /mnt/storage_pool/testnfs01 # * 6 0x06fd0000000000000000000000000000 * 6 0x05fd0000000000000000000000000000 /mnt/storage_pool/testnfs05 * 6 0x04fd0000000000000000000000000000 /mnt/storage_pool/testnfs04 # * 6 0x09fd0000000000000000000000000000 # * 6 0x08fd0000000000000000000000000000 # * 6 0x07fd0000000000000000000000000000 When I mount "/mnt/storage_pool/testnfs07" which does not appear in the proc info , problem happens, I can not even mount from local machine. More info: 1. I use tcpdump and find that STALE returns when FSINFO call during mount procdure, please check the attached screenshot. 2. I debug nfsd, and find that FSINFO fail stack: cache_check() return -ENOENT or -EAGAIN exp_find_key() exp_find() rqst_exp_find() nfsd_set_fh_dentry() fh_verify() nfsd3_proc_fsinfo() Please help me, my kernel is still 2.6.35.6. Looking forward for your reply! Thanks!
