I have a problem, I think I wrong to edit /etc/fstab on centos7 and I cannot reboot my remote server.
I’m in rescue mode with freebsd.
I cannot mount my ada0s3 (on centos was sda3) to fix my fstab.
root@rescuefbsd:/mnt # gpart show -p ada0 => 63 3907029105 ada0 MBR (1.8T) 63 1985 - free - (993K) 2048 2048 ada0s1 linux-data (1.0M) 4096 1024000 ada0s2 linux-data [active] (500M) 1028096 3889223680 ada0s3 linux-data (1.8T) 3890251776 16777216 ada0s4 ebr (8.0G) 3907028992 176 - free - (88K) root@rescuefbsd:/mnt # file -s /dev/ada0s3 /dev/ada0s3: Linux rev 1.0 ext4 filesystem data, UUID=80281fb1-7589-4a01-b2d0-6e6529e6b09b (needs journal recovery) (extents) (64bit) (large files) (huge files) root@rescuefbsd:/mnt # dmesg | grep ada0 ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: <WDC WD2002FAEX-007BA0 05.01D05> ATA-8 SATA 3.x device ada0: Serial Number WD-WMAY02628053 ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 1907729MB (3907029168 512 byte sectors: 16H 63S/T 16383C) ada0: Previously was known as ad4 WARNING: mount of ada0s3 denied due to unsupported optional features WARNING: mount of ada0s3 denied due to unsupported optional features WARNING: mount of ada0s3 denied due to unsupported optional features WARNING: mount of ada0s3 denied due to unsupported optional features
Tried (some solution on google):
root@rescuefbsd:/mnt # mount -t ext4 /dev/ada0s3 /mnt mount: /dev/ada0s3: Operation not supported by device root@rescuefbsd:/mnt # mount /dev/ada0s3 /mnt mount: /dev/ada0s3: Invalid argument root@rescuefbsd:/mnt # mount -t ext2fs -o ro /dev/ada0s3 /mnt mount: /dev/ada0s3: Invalid argument
Some idea please?
Answer
