Mir ist ein seltsames Phänomen aufgefallen, wenn ich eine große Anzahl kleiner Dateien (z. B. Hunderttausende Bilder) mit auf eine externe Festplatte übertrage rsync: Es führt immer zu einem IO-Fehler, wie unten gezeigt (Ausgabe von dmesg):
[102560.315796] blk_update_request: I/O error, dev sdc, sector 2088 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0

[102560.315979] Buffer I/O error on dev sdc1, logical block 5, async page read
Die Festplatte kann dann nicht mehr gemountet werden, aber jedes Mal, wenn dies passierte, konnte ich es mithilfe von reparieren, ntfsfixdaher bezweifle ich, dass es sich um ein Hardwareproblem handelt. ntfsfixDie Ausgabe wird unten angezeigt:
Mounting volume... $MFTMirr does not match $MFT (record 0).

NTFS partition /dev/sdc1 was processed successfully.
Ich bin also wirklich neugierig, was zu so häufigen Festplattenbeschädigungen selbst bei den einfachsten Datei-E/A-Vorgängen führen könnte. In den letzten zwei Tagen ist es über 20 Mal zu Festplattenbeschädigungen gekommen. Liegt es am System oder an rsyncder Festplatte selbst?
Ein weiteres seltsames Phänomen: Nach dem Synchronisieren vieler Dateien per rsync dauert das Unmounten der Festplatte sehr lange (~10 Minuten), auch wenn kein E/A-Fehler auftritt.
Ich verwende Ubuntu 20.04 und die Festplatte ist eine Seagate SDC003 (2 TB, als NTFS formatiert).
Update: Die Ausgabe von smartctl -a. Ich habe dies direkt nach einem weiteren rsyncFehler ausgeführt.
