I have a server running Slackware 11. The /home has been copied from an older server running an ancient version of Slackware with kernel 2.2. The problem is that the quota system has changed in the meantime and this is causing some bugs (notably aberrant disk usage measurements for some users, resulting in locked accounts).
I've searched the web and found out the command convertquota to upgrade quota files to the new version. Unfortunately, the use of
convertquota -uvf /home
results in the following error message:
convertquota: Can't open quotafile /home/quota.user: permission denied
convertquota: Can't open old format file for users on /home
I have of course checked permissions on /home/quota.user (that is 751, with file belonging to root), not to mention that the command was launched as root.
I would really be grateful if anyone could help me.
Note: I guess that the next step might be to find an oportunity to switch the server off and to reboot it from a CD so that the filesystem won't be in use ?
