    Free inodes < 10% on volume /opt/zimbra/backup

    Hi guys

    I've set up a Zimbra 8.6 test environment with Zextras. Last week I created and deleted a lot of accounts to test an application which drive zimbra provisioning in SOAP. I may have created and deleted 7500 accounts three or four times on a single store installation.

    This morning I've got an alert because remaining inodes on zextras backup folder is very low. Space used is only 25 % but the folder /opt/zimbra/backup/zextras/accounts is 2.3 Go :

    Code:
    Filesystem            Size  Used Avail Use% Mounted on
    lv_zimbra_backup      9,8G  2,3G  7,4G  24% /opt/zimbra/backup
    
    Filesystem           Inodes IUsed IFree IUse% Mounted on
    lv_zimbra_backup     640K  564K   77K   89% /opt/zimbra/backup
    I have two questions :
    - In production (8 stores) should I do something like set inode size higher ?
    - How can I reset zextras backup folder (lose all backup and start from zero but without losing zimbra mailstores data) ?

    Code:
    # tune2fs -l /dev/mapper/vg_lxlyofcs320_data-lv_zimbra_backup

    Hello Victor!

    Resetting the backup path is as easy as deleting all of its contents - everything ZeXtras Backup saves it's stored there so you don't have to worry about leftover data in your disk or database.


    About the inode size, that's heavily dependent on both the size of the filesystem and its usage - the only property I suggest to evaluate to change is the inode_ratio, since the Backup Path creates a large number of small files when storing the metadata, but I wouldn't do that unless going for an extreme optimization (which would require real-life testing, since this kind of tests are influenced by the size of the filesystem).


    Have a nice day,

    Hello Cine

    Thanks for your reply. Deleting the zextras backup folder worked well without need of restart Zimbra.

    Regards
