Fixing the broken/corrupt Locker Partition on Esxi

Fixing the broken/corrupt Locker Partition on Esxi

Sometimes can occur an esxi corrupted partition that can appear with error mounting vmware tools iso


To resolve this issue, you must connect via ssh to host and than follow the below guide

commands: 
ls -ltrh / | grep store
 vmkfstools -P /vmfs/volumes/5cdce747-375af1f6-b185-0050569674de
 
Output: 
ls -ltrh / | grep store 
lrwxrwxrwx    1 root     root           6 May 13 23:03 locker -> /store lrwxrwxrwx    1 root     root          49 May 16 04:29 store -> /vmfs/volumes/5cdce747-375af1f6-b185-0050569674de 

vmkfstools -P /vmfs/volumes/5cdce747-375af1f6-b185-0050569674de
vfat-0.04 (Raw Major Version: 0) file system spanning 1 partitions.

Partitions spanned (on "disks"):
        mpx.vmhba0:C0:T0:L0:8
Is Native Snapshot Capable: NO 

Make a note of the device under the line Partitions spanned (on “disks”):

Note: The :8 on the above result signific that this is partition 8 of the disk
Note: On a default install, the locker/tools iso are always stored to partition 8 of the installed disk/drive.

Format the partition with fat filesystem using the below command: Ensure you DO NOT MISS the partition number

vmkfstools -C vfat /dev/disks/mpx.vmhba0:C0:T0:L0:8
eg: 
vmkfstools -C vfat /dev/disks/mpx.vmhba0:C0:T0:L0:8
create fs deviceName:'/dev/disks/mpx.vmhba0:C0:T0:L0:8', fsShortName:'vfat', fsName:'(null)'
deviceFullPath:/dev/disks/mpx.vmhba0:C0:T0:L0:8 deviceFile:mpx.vmhba0:C0:T0:L0:8
Checking if remote hosts are using this device as a valid file system. This may take a few seconds...
Creating vfat file system on "mpx.vmhba0:C0:T0:L0:8" with blockSize 1048576 and volume label "none".
Successfully created new volume: 5cdcf45e-68f98eec-adb0-0050569674de

Note: If the format fails with the resource in use errors, the host will need a reboot.

re-create the symlink for store:

ln -snf /vmfs/volumes/5cdcf45e-68f98eec-adb0-0050569674de /store

ln -snf /vmfs/volumes/5cdcf45e-68f98eec-adb0-0050569674de /locker

Copy contents of the store partition from a working host, same Esxi build
