Hi Fabio,
I suggest you get and build the latest version from github or
sourceforge repository.
Indeed, there is a recent fix that sounds like your issue:
625df4e Fix possible crash in db_exec_sql
# git clone https://github.com/cea-hpc/robinhood.git
# cd ./robinhood.git
# ./configure
# make rpm
The error in the logs looks like an invalid/inconsistent value for
"nlink", but it is not obvious it is related to the segfault.
Error 7 executing query 'UPDATE ENTRIES set nlink=nlink-1 where
id='0x2363d5eca:0xf403:0x0'': BIGINT UNSIGNED value is out of range in
'(`rbhxxx`.`ENTRIES`.`nlink` - 1)'
I suggest you:
1) check if this entry still exists. Execute:
lfs fid2path /your/fs/mnt 0x2363d5eca:0xf403:0x0
2) if not, delete the entry from robinhood DB:
> mysql rbh_db
delete from ENTRIES where id='0x2363d5eca:0xf403:0x0';
delete from NAMES where id='0x2363d5eca:0xf403:0x0';
delete from ANNEX_INFO where id='0x2363d5eca:0xf403:0x0';
Regards,
Thomas
