Raid nach Booten öffnen und mount

Um Auto-Assembly beim Booten zu verhindern muss die Config-Datei /etc/mdadm.conf leer (oder zumindest komplett auskommentiert sein) und "MDADM_SCAN=no" in /etc/sysconfig/mdadm

1.) Checken ob alle Platten da sind: 

/root/bin/diskserial_sort2.sh

Müssen im Moment 17 Platten sein.

2.) Raids suchen und assemblen (kein Autostart): 

mdadm --assemble --scan

3.) Cryptsetup: 

cryptsetup luksOpen /dev/md125 cr_md125

4.) Mounten: 

mount /dev/mapper/cr_md125 /data

Schliessen wäre: 

cryptsetup luksClose cr_md125

Samba-Freigabe

There's a bug in Samba in openSuse 11.4. Here's the workaround: 

   go to Yast --> AppArmor --> Control Panel (on) --> Configure Profile Modes --> usr.sbin.smbd = complain
   go to Yast --> system --> runlevels --> smb=on + nmb=on
   reboot

Direkte Netwerkverbindung Store1 <-> Store 2.0

du kannst auch mal schauen was in /etc/udev/rules.d/70-persistent-net... (oder wie auch immer die date heißt) steht.

da wird die mac einer bestimmten netzwerkadresse (eth0, eth1, ...) zugewiesen.

die datei kannst du auch löschen oder verschieben - wird beim neustart neu angelegt.

da kommt machmal was durcheinander - bei 'nem kernelupdate oder bios-update.

GEHT ! unterschiedliche subnets (192.168.2.100 und 192.168.2.102)

What you are seeing are the Normalized Attribute values changing.

For example when the Raw_Read_Error_Rate changed from 99 to 100, the increase in Normalized value from 99 to 100 means that the disk now thinks it is a bit LESS likely to fail than before, because this Normalized value is moving further above the (low) Threshold value.
