I have one issue related to GPFS filesystem. We have bad entries in this file system, which reflects error like
Code:
ls: 0653-341 The file <filename> does not exist.
when we give "ls -ltr" on this directory.
So we taken the FS filesystem offline and followed the below steps.
Code:
root@profrd06:/root]# umount /opt/minotaur/Data/Shared_CFDX
root@profrd06:/root]# mmfsck /dev/gpfslv
Checking "gpfslv"
Checking inodes
Checking inode map file
Checking directories and files
Error in directory inode 461241: DirEntryBad
Directory entry "GSM_20080821022010_MSC140547280551273.EDR" is not an allocated inode.
Patching will delete the directory entry.
Remove directory entry? y

File inode 1191665 is not referenced by any directory.
Reattach inode to lost+found? y
File inode 1196881 is not referenced by any directory.
Reattach inode to lost+found? y
And it gave the result similar as above. However it has removed all the files who have bad entries.
But the corruption issues was because of the old version of IBM servers so their typical workaround is to do patching , and its 2 years old, so lot of patching is require and will be blind in production servers. So anyway cant go for it (not recommended).
Kindly let me know if any is familiar about any alternate on this, the details are as below :
Code:
<username@hostname> $ uname -a
AIX <hostname> 3 5 00C0B4204C00
Kindly let me know if something else is required.
