Hello,
Perhaps someone has seen a similar issue? If so any insight would be
appreciated.
We recently migrated some websites from an NFS share by which the NFS
server is exporting a share sitting on a Lustre mount. Below is the issue.
- sftp a file to website.ca - the load balancer will direct session to
server1 or server2, let us say server1 in this case
- Accessing the file with Apache via server1 works but via server2 a NFS
EIO -13 error is encountered
- On server1 (or server2) copy the file to /dev/null makes the file
accessible to Apache on either server1 or server2
- As work around sftp file to a temporary location, then ssh into
website.ca and "cp tmp/file.jpeg www/file.jpeg", this allows then
Apache on either server1 or server2 to access the file
- Created an lseek C program to try mimicking a captured Apache strace
but it shows success on any combination of file access scenarios
Prior to adding in Lustre no such such issues were encountered.
Thanks,
