是不是你在安装12.04分区的时候，只定好了/，其他的几个分区虽然存在，但是没有修改一下，分配为/home或者/usr？ 建议重装…… <div class="gmail_quote">2012/5/7 Pointer Royden <<a href="mailto:pointertopointers@gmail.com" target="_blank">pointertopointers@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">前几天刚装的ubuntu12.04，替换了以前的ubuntu。今天才发现一个很严重的问题。。 原来我是给ubuntu分了/ /home /swap /usr四个分区的。。但是现在 *代码:* [rhythmx@Lawliet ~]$ df -h 文件系统容量已用可用已用% 挂载点 /dev/sda10 24G 8.9G 14G 41% / udev 1000M 4.0K 1000M 1% /dev tmpfs 403M 908K 402M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1007M 1.4M 1006M 1% /run/shm none 1007M 33M 975M 4% /tmp/guest-JjZtmt 我给之前的ubuntu分的分区都没了，只剩下sda10挂载到/上。。 *代码:* [rhythmx@Lawliet ~]$ sudo fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x624aa2e0 Device Boot Start End Blocks Id System /dev/sda1 * 2048 65548287 32773120 7 HPFS/NTFS/exFAT /dev/sda2 65548288 275263487 104857600 7 HPFS/NTFS/exFAT /dev/sda3 275263488 484978687 104857600 7 HPFS/NTFS/exFAT /dev/sda4 484980734 625141759 70080513 f W95 Ext'd (LBA) /dev/sda5 484980736 491374591 3196928 b W95 FAT32 /dev/sda6 491376640 492400639 512000 83 Linux /dev/sda7 492402688 492900351 248832 83 Linux /dev/sda8 541730816 623187967 40728576 83 Linux /dev/sda9 623190016 625141759 975872 82 Linux swap / Solaris /dev/sda10 492902400 541728767 24413184 83 Linux Partition table entries are not in disk order 从sda1到sda5是windows， sda6到sda9都没挂载。。就是说我那些分区根本没用到，现在的系统只用到了sda10, 只有/一个分区 现在我怎么继续用那些分区啊。。 ----- There is neither happiness nor misery in the world; there is only the comparison of one state to another, nothing more. He who has felt the deepest grief is best able to experience supreme happiness. We must have felt what it is to die, that we may appreciate the enjoyments of life. ' Live, then, and be happy, beloved children of my heart, and never forget that until the day when God shall deign to reveal the future to man, all human wisdom is summed up in these two words - "Wait and hope."
