Aix Mount


This is the accepted answer. mrmzng replied Feb 21, 2013 Hi Mac! Answer While AIX PowerHA can give concurrent access of volume groups to multiple systems, mounting a JFS2 filesystem on multiple nodes simultaneously will cause filesystem corruption. Local fix Only workaround is to turn mount guard off which is not recommended. Check This Out

Subscribe You can track all active APARs for this component. Just two questions about this: 1) What's the difference between importvg and recreatevg? This is for my own good? The filesystem is potentially mounted on another node After a system crash the filesystem may still have mount flags enabled and refuse to be mounted.

Aix Mount

Question: normally many specialists are using raw device for database.... The only exception to this is mounting the filesystem read-only, where files or directories can't be changed. The success was announced by the following message: /SImg/epic/prd01 is no longer guarded against concurrent mounts.

On the backup server when we try to mount filesystems, we get this error : mount /echange mount: /dev/echangelv on /echange 0506-365 Cannot mount guarded filesystem.

If mountguard is enabled by the chfs or crfs command, the filesystem cannot be mounted if it appears to be mounted on another node or system.

About Emre Özkan I live in Istanbul/TURKEY and working with Anadolubank.,I am Unix & Backup & Storage Admin in this company. The herald of a failure was announced with: mount: /dev/SImg/epiceve on SImg/epicevent Cannot mount guarded filesystem.

ShadowImage process executed against each mirror duplicated the data including all the “description areas”. Log in to reply. All rights reserved. navigate here This has been confusing analysis of root cause in HACMP problems and flash copy problems.

In my case I was not using EMC Recoverpoint, instead I am cloning the LUNs with EMC snapview commands sent to CLARiiON storage. Mount Guard is not enabled by default, but is configurable by the system administrator. APAR status Closed as program error. Unless you're performing some modifications on them, I expect they're just being used for backups.

The issue was fixed running an fsck on the filesystems and mounting them ro (read only) later. You are going to receive something absolutely free. Everything you explained step by step was detailing my exact problems and the end solution worked for me successfully. Log in to reply.
