मैं कॉम्पैक्ट फ्लैश मीडिया पर EXT4 प्रदर्शन पर कुछ बेंचमार्किंग कर रहा हूं।
मैंने 65536 के ब्लॉक आकार के साथ एक एक्स 4 एफ बनाया है। हालांकि मैं नहीं कर सकता इसे ubuntu-10.10-netbook-i386 पर माउंट करें। (यह पहले से ही ब्लॉक आकार के 4096 बाइट्स के साथ ext4 एफएस बढ़ रहा है)
Ext4 पर मेरे रीडिंग के अनुसार इसे ऐसे बड़े ब्लॉक आकार की अनुमति देनी चाहिए FS। मैं आपकी टिप्पणी सुनना चाहता हूं।

mount: wrong fs type, bad option, bad superblock on /dev/sda3,

In some cases useful info is found in syslog - try

के अनुसार यह जवाब ऐसा लगता है कि आप इसे फ्यूज- ext2 के साथ माउंट कर सकते हैं
