我对OVH上托管的VPS进行了升级,特别是从VPS CLOUD 1升级到VPS CLOUD 2,其中先前的解决方案多了25gb(总共50gb).
在这个VPS上安装了CentOS 7.2.1511
有df -HT的结果
[root@srv ~]# df -HT File system Tipo Dim. Usati Dispon. Uso% Montato su /dev/vda1 xfs 27G 12G 16G 42% / devtmpfs devtmpfs 2,1G 0 2,1G 0% /dev tmpfs tmpfs 2,1G 0% /dev/shm tmpfs tmpfs 2,1G 18M 2,1G 1% /run tmpfs tmpfs 2,1G 0% /sys/fs/cgroup tmpfs tmpfs 405M 0 405M 0% /run/user/0
有fdisk -l |的结果grep磁盘
[root@srv ~]# fdisk -l | grep Disk Disk /dev/vda: 53.7 GB,53687091200 bytes,104857600 sectors Disk label type: dos
其他磁盘信息：
[root@srv ~]# fdisk -l /dev/vda Disk /dev/vda: 53.7 GB,104857600 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 label type: dos Identificativo disco: 0x000af71d Dispositivo Boot Start End Blocks Id System /dev/vda1 * 2048 52428799 26213376 83 Linux
我试过这个：
[root@srv ~]# xfs_growfs /dev/vda1 -D 53.7G Meta-data=/dev/vda1 isize=256 agcount=13,agsize=524224 blks = sectsz=512 attr=2,projid32bit=1 = crc=0 finobt=0 data = bsize=4096 blocks=6553344,imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=0 log =internal bsize=4096 blocks=2560,version=2 = sectsz=512 sunit=0 blks,lazy-count=1 realtime =none extsz=4096 blocks=0,rtextents=0 data size 53 too small,old size is 6553344
还有这个：
[root@srv ~]# xfs_growfs -d /dev/vda1 Meta-data=/dev/vda1 isize=256 agcount=13,projid32bit=1 = crc=0 finobt=0 spinodes=0 data = bsize=4096 blocks=6553344,rtextents=0 data size unchanged,skipping
显然没有成功.
[UPDATE]
part上的pr命令输出：
Modello: Device a blocchi Virtio (virtblk) Disco /dev/vda: 53,7GB Dimensione del settore (logica/fisica): 512B/512B Tabella delle partizioni: msdos Flag del disco: Numero Inizio Fine Dimensione Tipo File system Flag 1 1049kB 26,8GB 26,8GB primary xfs avvio 2 26,8GB 53,7GB 26,8GB primary xfs
如何在不破坏数据的情况下扩展可用磁盘空间？重启服务器不是问题.
xfs_growfs -d / dev / vda1
原文链接：https://www.f2er.com/centos/373636.htmlCapital -D增长到指定大小in filesystem blocks,它不理解’G’.因此它假设你想要53个文件系统块,但是失败了.
小写-d增长到最大尺寸.
如果你想要特定的尺寸,你应该在块中计算它,例如从fdisk输出,最大大小为26213376.然后-D 26213376也将从现在的6553344个块增加到最大值.
