STABILITÄT Store 2.0

Vermutung: Die drei SATA-Erweiterungskarten crashen gelegentlich das komplette System.

Karten: 

http://www.sybausa.com/productInfo.php?iid=537

Syba SY-PEX40008 4-port SATA II PCI-e Software RAID Controller Card--Bundle with Low Profile Bracket, SIL3124 Chipset Sind die identischen Karten, die immer noch von Backblaze verbaut werden (Pod 2.0 UND Pod 3.0!)

RAID bliebt heile (zum Glück!), da die Karten dann komplett die Zugriff sperren.

Arch-Log files haben gar keine Einträge zu den Crashs!!!

Remote-Log über Syslogd (über Myth) zeigt als letzten Eintrag: 

 sata_sil24: IRQ status == 0xffffffff, PCI fault or device removal

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. Basis ist die Datei disknum.txt unter /root/bin

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

Festplatte vorbereiten 

Open gdisk with the first hard drive:

$ gdisk /dev/sda

and type the following commands at the prompt: 

   Add a new partition: n
   Select the default partition number: Enter
   Use the default for the first sector: Enter
   For sda1 and sda2 type the appropriate size in MB (i.e. +100MB and +2048M). For sda3 just hit Enter to select the remainder of the disk.
   Select Linux RAID as the partition type: fd00
   Write the table to disk and exit: w

Bad Blocks

badblocks -vs -o sdy-badblock-test /dev/sdy

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.

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.
