ASA5505 error writing to flash file system

Phil Williamson

Any idea how to work around this error/problem?

ciscoASA5505# reload
System config has been modified. Save? [Y]es/[N]o:Y
%Error opening disk0:/.private/startup-config (Read-only file system)
Error executing command
Proceed with reload? [confirm]
ciscoASA5505#

I'm remote so formating the flash etc is not a good solution.

Thx,

Phil

When you perform the reformat, it will repair the faulty file system. If that can't be repaired, you would need to replace the flash.

Unfortunately you only have 2 options in this situation:

1) Reformat the flash

OR/

2) Reload the ASA

Unfortunately none of them is a good solution when you are remote to the ASA.

I was afraid that was my only option.

Actually the unit has been reloaded since the error first appeared, but it persists.

Is is possible to format flash, tftp new IOS/ASDM and startup-config and reload with some assurance that I don't end up with an 'electronic brick'?

When you have issues with your flash, check your flash with fsck.

asafw# fsck disk0:

dosfsck 2.11, 12 Mar 2005, FAT32, LFN

/csco_config/97/bookmarks/Template

  Contains a free cluster (5131). Assuming EOF.

/csco_config/97/bookmarks/Template

  File size is 881 bytes, cluster chain length is 0 bytes.

  Truncating file to 0 bytes.

Reclaimed 4 unused clusters (32768 bytes) in 2 chains.

Performing changes.

/dev/hda1: 57 files, 12873/31180 clusters

fsck of disk0: complete
