Hallo zusammen,

ich habe 5 der Seagate NAS HDDs in meinem Server, 2 als Mirror und 3 als Raidz1.
Ich hatte zuerst nur den Mirror in Betrieb und habe nachträglich die 3 Platten für Raidz1 gekauft.
In der Zeit als nur die beiden Platten liefen habe keine beunruhigenden Geräusche festgestellt, was sich allerdings mit der Inbetriebnahme der weiteren 3 Platten geändert hat.
Gefühlt rattert eine Platte extrem, allerdings weiß ich nicht welche, da ich das Raidz1 ja nicht einfach zerpflücken kann (bzw. sollte)
Laut den S.M.A.R.T. Daten würde ich auf da4 tippen, da hier die Seek_Error_Rate extrem nach oben schnellt.
Das Raidz1 ist auch langsamer als der Mirror, was ich eigentlich nicht erwartet hatte.
Mirror ca. 90-100 MB/s
Raidz1 ca. 50-60 MB/s
Oder ist das normal mit einem Xeon E3 1230v3 und 16 GB ECC RAM auf einem Supermicro X10SL-7F alle 5 Platten sind an dem LSI-SAS2308 angeschlossen.
Anbei noch die S.M.A.R.T. Daten der 5 Platten.

Die Frage ist hier, ob ich mir Gedanken machen sollte, oder ob das eher normal ist?
Noch sind die Platten recht frisch, das System soll ja noch ein wenig länger halten.

Vielen Dank und Gruß

Wenn Du diese Anzeige nicht sehen willst, registriere Dich und/oder logge Dich ein.
Das ist normal, Seagate zählt bei den Attributen die Fehler nur in den ersten (linken) beiden Bytes und die Anzahl der Vorgänge in den restlichen 4 Bytes. Ob und wie viele Fehler es gab, ist natürlich nur bei einer hexadezimalen Anzeige der Rohwerte sofort zu erkennen.

Das ein RAID 5 (das ist ein RAIDZ1 ja) beim Schreiben langsamer ist, ist normal und liegt an der Write Penalty und natürlich werden durch das Stripping die Zugriffe auf eine RAID 5 ganz anders als bei einem RAID 1. Wenn Du dynamisch von einem zu anderen konvertierst (keine Ahnung ob das berhaupt geht), dann gibt es derweil auch viele Zugriffe auf die Platten um die Daten umzusortieren, in der Zeit sind mehr Lärm und eine schlechte Performance auch normal.

- - - Updated - - -

Die Ermittlng der Aktuellen Werte dieser Attribute funktioniert mehr oder weniger nach dieser Formel für die Suchfehler:
normalised SER = -10 log (lifetime seek errors / lifetime seeks)

In the above formula, if the drive has recorded no errors, then we would still need to set the number of errors to 1, otherwise the result would be indeterminate.

The following table correlates the normalised SER against the actual error rate:

90 — <= 1 error per 1000 million seeks
80 — <= 1 error per 100 million
70 — <= 1 error per 10 million
60 — <= 1 error per million
50 — 10 errors per million
40 — 100 errors per million
30 — 1000 errors per million
20 — 10 errors per thousand
Zum Vergrößern anklicken....
Wie man sieht, muss auch erst eine bestimmten Anzahl von Vorgängen erfolgt sein, bevor der Aktuelle Wert überhaupt so errechnet wird, ist dieser erreicht fällt er und steigt dann wieder, sofern es nicht keine/nicht zu häufig Fehler. Da es meine ich eine Millionen Vorgänge sind und die meisten der Platte z.B. noch keine 1 Millionen Lesevorgänge hinter sich haben, steht der plötzlich Abfall des Aktuellen Wertes auf etwa 60 wegen der Anwendung dieser Formel bei ihnen noch bevor. Also nicht erschrecken, wenn da plötzlich 60 statt 100 steht, die sind deswegen nicht schlechter geworden, die dürfte dann nur die erste Millionen zusammen haben und die erste ist ja immer die schwerste.

- - - Updated - - -

Auchso: Fehler habe ich soweit keine gesehen und denk aber dran: RAIDs ersetzen keine Backups! Auch keine RAIDZ von ZFS, dafür gibt es immer noch genug andere Risiken den Platten die einem Gehäuse sitzen, am selbst Netzteil hängen, von gleichen Filesystem verwaltet werden, etc. ausgesetzt sind, auch den ungewollten Aktionen des Users, der in einem unachtsamen Moment einen Fehler macht und dann sind wichtige Daten plötzlich weg. Daten von RAID und den Backupplatten gleichzeitig versehentlich zu löschen ist schon weiteraus schwerer.
 
Mich hatte eher der Raw_Value Wert verunsichert, da dieser ja extreme von den anderen abweicht.

Möglicherweise wurde gerade noch von einer anderen Stelle auf den Share zugegriffen, als ich den Speedtest mit dem Raidz1 gemacht haben, nachdem ich jetzt NIC Teaming aktivert habe komme ich auch hier auch gute 90-100Mb/s.
