Non-removeable file in EOS after drain

Site Administrators
1

Hello,

We are running a drain and some files cannot be transferred. It was decided to clean them. For this, a standard command

eos rm <file>

was used. After that, the drain was run again, but some files remained. The command

eos fs dumpmd $i --path

does not display the list of files and displays messages like this:

# warning: missing container for fxid=1aa85e88
# warning: missing container for fxid=1ac00b30
# warning: missing container for fxid=1ab60cec
# warning: missing container for fxid=1ac60bfe
# warning: missing container for fxid=1ab0e016

I tried to remove this containers like in this topic (LEADER eos-b01.jinr.ru:7777):

(https://eos-community.web.cern.ch/t/non-removeable-file-in-eos/708)

but nothing happened:

Please tell me how I can delete these containers?

Hello, Ivan.

Could you try fs dropghosts command?

As a manual, it can also use --fxid option to specify the file.

Hi, GeonmoRyu.
I tried:

eos fs dropghosts 58
success: dropped 0 ghost entries from fsid=58

and

eos fs dropghosts 58 --fxid fxid=1ac60bfe
success: dropped 0 ghost entries from fsid=58

but nothing happened.
