Re: [Ocfs2-users] High inodes usage
That number is typically calculated. So it just could be bad arithmetic. But that should not affect the other ops.

Re: [Ocfs2-users] High inodes usage
I don't know if it's the root cause of my problems or if it causes any problem at all. But I have some stability issues on the cluster so I'm investigating anything that could be suspect. My question is : is it a normal behavior to get inode usage with df -i showing high percentage like 98, 99 or 100%? (a touch on the filesystem with 100% inode usage still create a file so I suppose it is not causing any problem but I found it weird). 2013/7/3 Sunil Mushran > That is old.

Re: [Ocfs2-users] High inodes usage
Hello Sunil, I checked the inode usage with df -i I can't check the kernel version running on the system now because I'm not at work but it's a SLES 10 SP2, so a pretty old kernel I suppose.

[Ocfs2-users] High inodes usage
Hello guys, I'm using OCFS2 for a shared storage (on SAN). I just saw that the inode usage is really high although these filesystems are used for Oracle DATA storage. So there are really a few big files. I don't understand why the inode usage is so high with such few big files (As an example : one of the filesystem have 16 files and directories but the ~26 million of inodes are almost used!) My questions : - is the inode usage can be a problem in such a situation - if it is : how can I reduce their number used? Or increase the pool of available inodes? - why so many inodes are used with such a few files? I was sure that there were traditionaly one inode used for one file or one directory. -- Nicolas MICHEL ___ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com https://oss.oracle.com/mailman/listinfo/ocfs2-users
