ACFS Input/output error on OS kernel 3.10.0-957
October 14, 2019 Leave a comment
Problem:
My ACFS volume has intermittent problems, when I run ls
command I get ls: cannot access sm: Input/output error
and user/group ownership contains question marks.
[root@primrac1 GG_HOME]# ll ls: cannot access ma: Input/output error ls: cannot access sm: Input/output error ls: cannot access deploy: Input/output error total 64 d????????? ? ? ? ? ? deploy drwx------ 2 oracle oinstall 65536 Sep 28 21:05 lost+found d????????? ? ? ? ? ? ma d????????? ? ? ? ? ? sm
Reason:
Doc ID 2561145.1 mentions that kernel 3.10.0-957 changed behaviour of d_splice_alias interface which is used by ACFS driver.
My kernel is also the same:
[root@primrac1 GG_HOME]# uname -r 3.10.0-957.21.3.el7.x86_64
Solution:
Download and apply patch 29963428 on GI home.
[root@primrac1 29963428]# /u01/app/19.3.0/grid/OPatch/opatchauto apply -oh /u01/app/19.3.0/grid
